Fix support for i.MX93 voltage modes on phyCORE-i.MX93 SoM boards.
First of all, Kconfig option CONFIG_IMX9_LOW_DRIVE_MODE is gone since
commit c9efcad23741 ("imx93_evk: Remove CONFIG_IMX9_LOW_DRIVE_MODE and
ld defconfig") and was replaced by runtime detection mechanism. Thus
lets use is_voltage_mode() instead of Kconfig to detect CPU type and
select proper voltage mode.
Secondly, 1400MHz ND mode (Nominal Drive) requiring 0.85V BUCK voltage
was not supported with current power_init_board() PMIC settings. Add
check also for this CPU type and set BUCK voltage accordingly.
Last but not least, add printf() printouts about PMIC voltage mode to
the console. This makes it more apparent and verbose about voltage mode
in use. Also our internal tests depend on this printout to catch issues
with i.MX93 CPU types and set PMIC voltage modes.

Switch to use CONFIG_PHYTEC_EEPROM_BUS instead of the hard coded value
of 2 for the EEPROM I2C bus for both SPL and U-Boot proper. Possible
since commit 88a1816a9b4e ("board: phytec: common: Add PHYTEC_EEPROM_BUS
to Kconfig").

Fix PHYTEC EEPROM bus mismatch between SPL and U-Boot proper by enabling
CONFIG_SPL_DM_SEQ_ALIAS=y on phyCORE-i.MX93 boards. This way, both the
SPL and U-Boot proper will respect the device-tree aliases for I2C devs
and use the same I2C bus number for phytec_eeprom_data_setup() function
calls. This makes code less confusing and more robust.
Fixes an issue apparent since commit 79f3e77133bd ("Subtree merge tag
'v6.16-dts' of dts repo [1] into dts/upstream") where SPL would spew the
following error:
phytec_eeprom_read: i2c EEPROM not found: -110.
phytec_eeprom_data_setup: EEPROM data init failed
While later in U-Boot proper, EEPROM would be successfully read out.
This happens because Linux device-tree for phyBOARD-Segin-i.MX93 since
aforementioned commit enables I2C bus 2 (lpi2c2 is used for audio codec
and RTC) which breaks SPL I2C bus number ordering and I2C EEPROM bus is
shifted by +1. Now, lets prevent this from happening again by utilizing
device-tree aliases also in the SPL.

The phyCORE-i.MX 93 is available in various variants. Relevant variant
options for the spl/u-boot are:
- with or without HS400 support for the eMMC
- with 1GB ram chip, or 2GB ram chip
The phyCORE's eeprom contains all information about the existing variant
options. Add evaluation of the eeprom data to the spl/u-boot to
enable/disable HS400 and to select the appropriate ram configuration at
startup.

Since we use SPEED GRADE fuse to set A55 frequency, remove the
set_arm_core_low_drive_clk function which has hard coded frequency.
And adjust clock_init called sequence and split it to early and late
functions.
Set the authen register in early function, because CCF driver checks
NS bit.
Set bus and core clock in late function, because the fuse read and
SoC type/rev depend on ELE.
