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
