RZ/G2L SDHI has 4 clocks which is controlled by PM frame work and is using
Gen3 compatible string. Now the clock factorisation happened on highspeed
clock handling and it changes to fallback by getting parent clock, if
"clkh" is not specified in device tree.
This path series rename the clocks to match with the clock names used in
R-Car Gen2 and later generations. This will avoid driver changes related
to clock names.
This patch series based on renesas-devel

Rename the below RZ/G2L clocks to match with the clock names used in
R-Car Gen2 and later generations.
imclk->core
clk_hs->clkh
imclk2->cd
This changes will avoid using fallback for RZ/G2L high speed clock,
if "clkh" is not used in device tree and also the code changes in
driver related to this clocks.

The bindings match what we discussed. Thanks!

i.e. will queue in renesas-devel for v5.17 if Ulf is happy.
