clk: renesas: Add RZ/G2L & RZ/G2LC CPG driver

This driver provides clock and reset control for the Renesas R9A07G044L
(RZ/G2L) and R9A07G044C (RZ/G2LC) SoC. It consists of two parts:

* driver code which is applicable to all SoCs in the RZ/G2L family.

* static data describing the clocks and resets which are specific to the
  R9A07G044{L,C} SoCs. The identifier r9a07g044 (without a final letter)
  is used to indicate that both SoCs are supported.

clk_set_rate() and clk_get_rate() are implemented only for the clocks
that are actually used in u-boot.

The CPG driver is marked with DM_FLAG_PRE_RELOC to ensure that its bind
function is called before the SCIF (serial port) driver is probed. This
is required so that we can de-assert the relevant reset signal during
the serial driver probe function.

This patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).
