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.

The MODEMR register offset changed on R8A779A0, make the MODEMR offset
configurable. Fill the offset in on all clock drivers. No functional
change.

Reinstate RPC clock on D3/E3 after Linux 5.12 synchronization.
The D3 and E3 clock drivers do not contain RPC clock entries
mainline Linux yet.

The clock driver used a heavy-handed approach where it turned off
all available clocks, while also possibly setting bits which are not
documented in the R-Car datasheet. Update the tables so that only
the bits which are documented are set or cleared when tearing down
the clock driver.
Note that the only clock left running before booting Linux are now
MFIC, INTC-AP, INTC-EX and SCIF2 / SCIF0 on V3x.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The Gen2 requires setting RMSTPCR before booting, while on Gen3 this
is thus far always zero. Split the tables so the RMSTPCR can be set
too.

Split the massive driver into smaller per-SoC drivers and pull the
common code into a separate file. This would allow configuring out
unnecessary clock drivers once the Kconfig changes are in and also
allow adding more clock tables easily.
