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 c9efcad237 ("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 88a1816a9b ("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 79f3e77133 ("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.

For phyCORE-i.MX93 SoMs with i.MX93 parts running in VOLT_LOW_DRIVE mode
(SoCs with speed grade fuse set to 900 MHz) reduce usdhc clocks from 400
MHz to 266 MHz. Do this in board code since global imx9 board_fix_fdt()
is not used in case of phycore-imx93 board since commit d3b9b79968
("board: phytec: imx93: Add eeprom-based hardware introspection").
While at it, add a note to ft_board_setup() function to inform that
fixup for Linux device-tree is taken care by ft_system_setup() in imx9
global arch/arm/mach-imx/imx9/soc.c implementation.

The phyCORE-i.MX 93 is available in various variants (e.g. different ram
sizes, eMMC HS400 yes/no). Enable hardware introspection for the
imx93-phyboard-segin_defconfig, so that during startup the SOM module
variant can be detected, and the hardware can be configured accordingly.
The resulting SPL and u-boot binary shall able to boot each
phyCORE-i.MX 93 module variant on each carrier board. Finally rename
imx93-phyboard-segin_defconfig to imx93-phycore_defconfig, to highlight
its SOM scope.

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
