The current imx8mp-dhcom-som.dtsi describes production rev.200 SoM,
add DT overlay which reinstates rev.100 SoM description to permit
prototype rev.100 SoMs to be used until they get phased out.

Add DT overlays to support additional DH i.MX8MP DHCOM SoM 660-100
population options with 1x or 2x RMII PHY mounted on PDK2 or PDK3
carrier boards.
Use SPL DTO support to apply matching SoM specific DTO to cater
for the SoM differences. Remove ad-hoc patching of control DT from
fdtdec_board_setup().

1. Convert all linker symbols to char[] type so that we can get the
corresponding address by calling array name 'var' or its address
'&var'. In this way, we can avoid some potential issues[1].
2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has
not been referenced by any source code.
3. Move '__data_end' to the arch x86's own sections header as it's
only used by x86 arch.
4. Remove some duplicate declared linker symbols. Now we use the
standard header file to declare them.
[1] This patch fixes the boot failure on MIPS target. Error log:

The FEC interface mode is now configured in common board_interface_eth_init()
and called by FEC MAC driver when appropriate. Drop the board side duplicates
if the same functionality.

The i.MX8MP DHCOM SoM may be populated with either KSZ9131RNXI RGMII PHY
or LAN8740Ai RMII PHY attached to EQoS MAC, and either external RGMII PHY
or LAN8740Ai RMII PHY attached to FEC MAC. The SoM configuration can be
detected for each MAC by reading RX_CTL pull resistor state early on boot.
Make use of this, detect the exact PHY configuration, and patch control DT
accordingly so that the ethernet is configured correctly in U-Boot.

The DH electronics i.MX8M Plus DHCOM SoM currently supports only 4 GiB
of DRAM population option. Add another population option with 2 GiB of
DRAM. The chips used on the 2 GiB option are 2x K4F6E3S4HM-MGCJ .

The PCA9450 reset configuration can now be performed by the PCA9450 PMIC
driver itself, remove the hard-coded variant from board code and let the
PMIC driver perform this task using one-liner:
```
$ sed -i '/set WDOG_B_CFG to cold reset/,+2 d' $(git grep -l PCA9450_RESET_CTRL.*0xA1 board/)
```
Venice and i.MX93 EVK required slight manual fix up.

Commit 99c7cc58e1 ("ddr: imx: Add i.MX9 DDR controller driver")
contains an inobvious side-effect which renders all systems using
DRAM controller at 3732 MT/s unbootable. The change is located in
ddrphy_init_set_dfi_clk(), where the switch case statement entry
3732 changed to entry 3733, so any board with DDR calibration data
for 3732 MT/s operations needs to be updated to 3733 MT/s to match
the change.
Since there is currently only one such board, update the board instead
of handling both 3732 and 3733 options in the driver. It is likely the
NXP MX8MP RPA update will follow and use the later value too.
