e41cb21793 clk: renesas: rcar-gen2: Rename vsp1-(sy|rt) clocks to vsp(s|r)
VSP1 instances VSPS (which stands for "VSP Standard") and VSPR (which
stands for "VSP for Resizing") were wrongly named as "vsp1-sy" and
"vsp1-rt". The clock section in the SoC datasheets misunderstood the
abbreviations as meaning VSP System and VSP Realtime, and named the
corresponding clocks VSP1(SY) and VSP1(RT). This mistake has been
carried over to the kernel code.

This patch fixes this by renaming the clock names to "vsps" and "vspr".

Inspired from commit 79ea9934b8 ("ARM: shmobile: r8a7790: Rename
VSP1_(SY|RT) clocks to VSP1_(S|R)")

6041ce57f2 clk: renesas: r8a7791/r8a7793: Fix LB clock divider
The CLK_TYPE_GEN2_LB clock type is meant for SoCs like R-Car H2, where
the LB clock divider depends on the value of the MD18 pin.

On R-Car M2-W and M2-N, the LB clock divider is fixed to 24.  Hence
model the clock as a fixed factor clock instead.

5ada6bee8c clk: renesas: r8a7791/r8a7793: Add rwdt clock
Add "rwdt" clock to r8a7791_mod_clks. Also, since we may need to access
the watchdog registers at any time, declare the clock as critical.

6449ab8141 clk: renesas: r8a7791/r8a7793: Add new CPG/MSSR driver
Add a new R-Car M2-W/N Clock Pulse Generator / Module Standby and
Software Reset driver, using the CPG/MSSR driver core.  This will enable
support for module resets, which are not supported by the existing
driver.

The old driver can still be used through a Kconfig option, to preserve
backward compatibility with old DTBs.
