DHCP and DHCPv6 use the same value defined in
https://www.iana.org/assignments/dhcpv6-parameters#processor-architecture
to encode the processor architecture type. We should only use a single
Kconfig symbol for both protocols.
Furthermore we should make the value customizable. This allows for instance
to choose between "x86 BIOS" or "x64 UEFI".
As "x86 BIOS" is encoded as 0, we should not use this value to switch
off transmission of the DHCP option. Use 0xFF instead.

In IPv6, the broadcast MAC address is not used. Instead, it should use
the multicast address (see RFC RFC2464).
Add IPV6_ALL_NODE_ETH_ADDR macro for clarity.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

RFC 5970 states that OPT_BOOTFILE_PARAM (option 60) can be
multiple parameters that start with a 16-bit length field followed
by the parameter. For example:
[ param-len 1 (16-bits) ] [ parameter 1 (variable length) ]
This fix ensure we're considering "param-len 1" in the parsing.

Adds DHCPv6 protocol to u-boot.
Allows for address assignement with DHCPv6 4-message exchange
(SOLICIT->ADVERTISE->REQUEST->REPLY). Includes DHCPv6 options
required by RFC 8415. Also adds DHCPv6 options required
for PXE boot.
Possible enhancements:
- Duplicate address detection on DHCPv6 assigned address
- IPv6 address assignement through SLAAC
- Sending/parsing other DHCPv6 options (NTP, DNS, etc...)
