fix(rcar4): assure SCIF and HSCIF clock are always enabled

Prior stages before TFA BL31 may shut down the SCIF or HSCIF clock.
Enable the SCIF or HSCIF clock again during console initialization,
to make sure those clock are running and prints can be produced on
serial console if necessary.

feat(rcar): split common SCIF code

feat(rcar): split common SCIF code

Move common SCIF code into drivers/renesas/common/scif/scif-common.c
and retain only SoC-specific console_rcar_init() in
drivers/renesas/rcar_gen4/scif/scif.c. This allows other SoCs to
reuse the common code and add only SoC specific glue code.

feat(rcar): replace static rcar_putc pointer with static register offsets

Replace static rcar_putc pointer with static register offsets to make
the driver more generic for future Renesas R-Car SoCs.

feat(rcar): replace static rcar_putc pointer with static register offsets

Replace static rcar_putc pointer with static register offsets to make
the driver more generic for future Renesas R-Car SoCs. Introduce new
function scif_console_set_regs() to assign SCIF registers into static
variables, and call scif_console_set_regs() based on MODEMR register
settings. Other SoCs might simply call scif_console_set_regs() with
fixed register offsets.

feat(rcar): add support for Renesas R-Car S4 / V4H / V4M

Add support for Renesas R-Car S4 / V4H / V4M , which are Gen4 SoC.
Add platform code, BL31 setup code, platform specific PSCI handlers,
CPU power driver, Gen4 (H)SCIF driver, and function to get canary for
stack protector. Unlike Gen3, the Gen4 uses only TFA BL31 during boot.

from multiple authors. SoB line from each author is included here,
the author of this commit is set to myself although that is most
certainly not accurate.
