Add the driver for the Airoha EN8811H 2.5 Gigabit PHY. The PHY supports
100/1000/2500 Mbps with auto negotiation only.
The driver uses two firmware files, for which updated versions are added to
linux-firmware already.
Based on the Linux upstream 8811 driver code(air_en8811h.c),
I have modified the relevant process to align with the U-Boot boot sequence.
and have validated this on Banana Pi BPI-R3 Mini.
The MD32 FW is currently stored in eMMC partition 1 on Banana Pi BPI-R3 Mini,
and it is loaded from there.

The TI DP83822 does have support for configurable RGMII RX/TX clock
shift, add support for parsing DT properties which describe the RX/TX
clock shift configuration and configuration of the matching bits in
RCSR register.
The shift is only configurable on DP83822, the other PHYs supported
by this PHY driver, namely DP83825/DP83826 variants, do not implement
this functionality and the RCSR bits used to configure the clock shift
are missing from those PHYs.
The shift is configurable separately for RX and TX path. Each path can
either enable the shift or disable the shift using single bit. In case
the shift is disabled, a delay of 0ns is added to the path, otherwise
a delay of 3.5ns is added to the path.
Note that the two RCSR bits 11 and 12 have inverted logic, RCSR bit 12
enables RX internal shift when SET, while RCSR bit 11 enables TX shift
when UNSET.

This reverts commit 431be621c6.
Section 3.3 of Reduced Gigabit Media Independent Interface (RGMII)
Version 2.0 (4/1/2002) details that a PHYs using a ~2ns internal delay
are referred to as RGMII-ID. This internal delay is optional.
Page 147-148 of the Marvell Doc. No. MV-S107146-U0 Rev. F details
timings of the RX/TX delays. We see that with the TX/RX_CLK delay
enabled, our RX/TX_CTL signal is shifted w.r.t CLK to reflect the delay
added.
In 431be62 there is no timing difference between RGMII and RGMII-ID, and
so programmers wanting to explicitly set their PHY to RGMII will find
that delay added anyway. This could throw off timing if that internal
delay is undesired.
We should be handling all 4 possible RGMII cases of PHY_INTERFACE_MODE:
RGMII, RGMII_ID, RGMII_TXID, and RGMII_RXID. Reverting 431be62
implements this.
See also m88e1111_config_init_rgmii_delays in the equivalent driver in
Linux (drivers/net/phy/marvell.c), which does not set these delays in
RGMII mode.
68e6eca was tested out on an 88E1512 PHY in RGMII-ID mode. This
reversion has been tested by myself on an 88E1518 in RGMII-ID mode. This
patch affects boards using this driver in "rgmii" mode, as the internal
delay will no longer be enabled. Namely kikwood-nsa310s.

Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by
adding a new net/lwip/ directory and the NET_LWIP symbol. Network
support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent
commits will introduce the lwIP code, re-work the NETDEVICE integration
and port some of the NET commands and features to lwIP.
SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols
that are part of NET (such as arp_init(), arp_timeout_check(),
arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be
added later.
Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP
because of dependencies on net_loop(), tftp_timeout_ms,
tftp_timeout_count_max and other NET things. Let's add a dependency on
!NET_LWIP for now.
SANDBOX can select NET_LWIP but doing so will currently disable the eth
dm tests as well as the wget tests which have strong dependencies on the
NET code.
Other adjustments to Kconfig files are made to fix "unmet direct
dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when
the default networking stack is set to NET_LWIP ("default NET_LWIP"
instead of "default NET" in Kconfig).
The networking stack is now a choice between NO_NET,
NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be
'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.

Setting the clock delay from the device tree settings

- The expected value in the device tree is suppose to be a
delay in picoseconds, but the driver only allowed an array index.
- Driver converted this array index to the actual delay in
picoseconds and tried to apply this in the device register. This
however is not a valid register value. The actual logic here was
reversed, it converted an register representation of the delay to
the device tree delay in picoseconds.
Only when the internal delays were NOT configured in the device tree
and they default value of 7 (=2000ps) was used, a valid value was
loaded in the register.
