feat(rcar): deduplicate plat_crash_print_regs

The plat_crash_print_regs code is functionally identical between
Renesas R-Car Gen3 and R-Car Gen4, deduplicate the code. Split
plat_crash_print_regs into plat_macros_cci.S and move the Gen3
specific plat_print_gic_regs macro into plat_macros_gic.S so it
can be pulled in only on R-Car Gen3.

fix(rcar3): clear TCR_EL1 at the BL2 entry point

According to ARM DDI0601 2025-06 [1] TCR_EL1, Translation Control
Register (EL1), all fields of TCR_EL1 do, on a Warm reset, (this
field) resets to an architecturally UNKNOWN value.

On some SoCs, after reset, this TCR_EL1 may not be 0, which in itself
is perfectly valid behavior. However, existing software may depend on
TCR_EL1 being 0, and the UNKNOWN value may confuse such software.

Reset TCR_EL1 to well defined value 0 at BL2 entrypoint to achieve
maximum compatibility.

fix: remove unused cpu_data related macros

There are no uses for CPU_DATA_PSCI_LOCK_OFFSET so it is removed.

PLAT_PCPU_DATA_SIZE is also unused in ST platforms and causes offsets
to mismatch when the linker garbage collects it. It is also removed.

CPU_DATA_PLAT_PCPU_OFFSET is also removed as its only use is in
rcar_lock_get() and related macros which are never called since all
calls of these macros lack an argument.

feat(rcar3): populate kaslr-seed in next stage DT

The SCEG CC6.3S which contains TRNG is only accessible from secure
world. Pull 8 random bytes out of the TRNG and pass them to the next
stage via DT fragment as /chosen/kaslr-seed property, so Linux can
use those random bytes to initialize KASLR in case it is compiled
with CONFIG_RANDOMIZE_BASE .

Linux before this patch prints early on boot:
KASLR disabled due to lack of seed

Linux after this patch prints early on boot:
KASLR enabled
