mmc: renesas_sdhi: remove manual clk handling
The SDHI driver en-/disabled its main clock on its own, e.g. during probe() and remove(). Now, we leave all handling to RPM. clk_summary before: sd0 1 1 0 12480000 0 0 50000 sdif0 2 2 0 12480000 0 0 50000 clk_summary after: sd0 1 1 0 12480000 0 0 50000 sdif0 1 1 0 12480000 0 0 50000 Reported-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Link: https://lore.kernel.org/r/20200519164251.5430-1-wsa+renesas@sang-engineering.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be>
