feat(rcar): rewrite console_renesas_register() in C

Replace assembler implementation of console_renesas_register() with
matching C implementation. Since it is now easily possible to pass
flags into console_renesas_register() and then onward to the console
initialization, adjust the signature of console_renesas_register()
and include the flags in it. Adjust both rcar_console_boot_init()
and rcar_console_runtime_init() to call console_renesas_register()
with its new combined set of parameters and drop console_set_scope()
invocation which is no longer needed, because the flags are passed
directly into console_renesas_register().

Drop console_renesas_flush() which is always a noop. Drop return
value from console_renesas_init() which is always 1.

refactor(rcar): rename console_rcar_ to console_renesas_ prefix for Renesas platform

Rename console_rcar_ to console_renesas_ prefix for SCIF-based console
driver to make it reusable by other Renesas platforms.

Due to the above renaming, function console_renesas_register is duplicated
in both scif.h and console.h, so it should be removed from scif.h

fix(rcar): enable intialisation code for EL3 to NS-EL1 handoff

Enable initialisation code for handoff from EL3 to NS-EL1 using the
INIT_UNUSED_NS_EL2 flag on both R-Car Gen3 and Gen4 SoCs. This is
used by cores which proceed directly from EL3 to NS-ES1 and have no
code in NS-EL2.

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: 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.
