feat(st): adapt stm32 linker scripts for clang

With Clang, the address inside a section does not seem relative to its
start address. Use ABSOLUTE keyword for those addresses.
For stm32 binary containing BL2 and its DT, we can use that as PIE is
not used (either disabled or used with BL2_IN_XIP_MEM).
This is still working with GCC.

feat(st): update stm32 linker scripts

Remove an extra dot for the .data section.
Use FILL(0) instead of *(.data*). There is nothing there matching this
expression and was just use to have a filler.

Remove an extra dot for the .data section.
Use FILL(0) instead of *(.data*). There is nothing there matching this
expression and was just use to have a filler. Use explicit FILL(0)
instead.

fix(stm32mp2): correct early/crash console init

The previous code used 64-bit registers as the target and source for
load and store operations on 32-bit hardware registers. In certain
cases (e.g., when using USART1 as the debug console), this could result
in deadlocks where the A35 gets stuck in a permanent loop due to test
conditions that are never fulfilled.

To resolve this issue, 32-bit registers are now used for these
operations.

fix(stm32mp2): correct early/crash console init

The former code, using x2 register, was removing the LPEN bit from UART
config register. So the UART clock is stopped as soon as the CA35 is in
CSleep. It was then displaying crap in Linux console.
The ands check instruction is replaced with a clearer tst instruction
directly with the bit to be tested.
