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.

Add xHCI entry into the clock tables, so that the xHCI USB driver
can enable the clock for the xHCI block via clock framework.

The MSTP registers were poked in boards/renesas/rcar-common/common.c
in arch_preboot_os hook thus far to shut down the clock before Linux
takes over. With DM, this is no longer needed and we can do the same
in the clock driver .remove callback. This patch adds such a .remove
callback for R8A7795 and R8A7796.

The SDxCKCR must be configured correctly, otherwise the SDIF can be
unstable. This is done in board files thus far, but those are going
away, so move the setting of SDxCKCR into the correct place.

The R8A7795 and R8A7796 tables use different constants to identify
clock in DT, so split the tables and use the correct constants on
R8A7795. This fixes UART clock misconfiguration on R8A7795.

Add clock driver for the RCar Gen3 R8A7795 and R8A7796 SoCs .
This driver allows reading out the clock configuration set by
previous boot stages and enabling and disabling clock using
the MSTP registers. Setting clock is not supported thus far.
