Add the module clock used by the SPI Multi I/O Bus Controller (RPC-IF)
on the Renesas R-Car V4H (R8A779G0) SoC.
While at it, fix table alignment in the definition of the related
RPCSRC internal clock.

- Correct the parent clocks for the High Speed Serial Communication
Interfaces with FIFO (HSCIF) modules on the R-Car V4H SoC.
Note that HSCIF0 is used for the serial console on the White-Hawk
development board.
As serial communication requires a clean clock signal, the High Speed
Serial Communication Interfaces with FIFO (HSCIF) is clocked by a clock
that is not affected by Spread Spectrum or Fractional Multiplication.
Hence change the parent clocks for the HSCIF modules from the S0D3_PER
clock to the SASYNCPERD1 clock (which has the same clock rate), cfr.

On R-Car V4H, all PLLs except PLL5 support Spread Spectrum and/or

Currently, determine_rate() is not doing any round operation
and due to this it always selects a lower clock source compared
to the closest higher one.
Support sd clk mux round operation by passing
CLK_MUX_ROUND_CLOSEST flag to clk_mux_determine_rate_flags().

A variable pointing to const isn't const itself. It'd have to contain
"const" keyword after "*" too. Therefore, cpg_pll_config cannot be put
to "rodata". Hence use __initdata instead of __initconst to fix this.

Renesas RZ/Five SoC has almost the same clock structure compared to the
Renesas RZ/G2UL SoC, re-use the r9a07g043-cpg.c file to add support for

SoC using #ifdef CONFIG_ARM64 and #ifdef CONFIG_RISCV checks.

The register block base pointer as stored in the reg member of the
rz_cpg structure is only used during initialization. Hence move
it to a local variable, and pass it as a parameter to
rz_cpg_register_clock().
After this, the data member is the only remaining member of the rz_cpg
structure, so the whole structure can be replaced by the data member.

As per RZ/G2L HW(Rev.1.10) manual, reset monitor register value 0 means
reset signal is not applied (deassert state) and 1 means reset signal
is applied (assert state).
reset_control_status() expects a positive value if the reset line is
asserted. But rzg2l_cpg_status function returns zero for asserted
state.
This patch fixes the issue by adding double inverted logic, so that
reset_control_status returns a positive value if the reset line is
asserted.
