Update R-Car Gen4 support in Gen3 clock driver. This patch renames the
V3U clock parts to Gen4 and extends them by new PLL2, PLL3, PLL4, PLL6
as well as SDSRC clock which use undocumented bits so far, and RPCSRC
clock which uses its own more capable divider table. The Gen4 module
standby and reset tables are also updated.
This patch makes use of union to alias Gen3 and more extensive Gen4
PLL tables, as the driver cannot ever be instantiated on hardware
that would identify itself as both Gen3 and Gen4.
The V3U clock driver is updated to match Gen4 clock driver behavior,
it is augmented with a more extensive PLL table and a valid MODEMR
register offset.
This supersedes "clk: renesas: Introduce R-Car Gen4 CPG driver"
from Hai Pham as the R-Car Gen3 and Gen4 clock core drivers are
extremely similar. That implementation was in turn based on Linux
commit 470e3f0d0b15 ("clk: renesas: rcar-gen4: Introduce R-Car Gen4 CPG driver")
by Yoshihiro Shimoda .

Add trivial reset driver extension to the CPG clock driver. The change
turns current CPG UCLASS_CLK driver instance into an UCLASS_NOP proxy
driver, which in turn binds both generic rcar3_clk UCLASS_CLK clock
driver as well as generic rcar_rst UCLASS_RESET reset driver to the
CPG DT node. This way, any other drivers which use the 'reset' DT
property can now obtain valid reset handle backed by a reset driver.
The clock tables have been updated to represent the CPG driver and only
implement the generic CPG proxy driver bind call, which binds the clock
and reset drivers.
The DM_RESET is now enabled for all R-Car Gen3 platforms.

Synchronize R-Car R8A779A0 V3U clock tables with Linux 6.1.7,
commit 21e996306a6afaae88295858de0ffb8955173a15 .
Rename CLK_TYPE_R8A779A0_ to CLK_TYPE_GEN4_ to match the new
clock tables. Add CLK_TYPE_GEN4_SD, CLK_TYPE_GEN4_RPC and
CLK_TYPE_GEN4_RPCD2 macros and handling into Gen3 CPG core.
