arch/sh/include/cpu-sh4/cpu/sh7786.h: In function ‘sh7786_mm_sel’:
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:21: warning: passing argument 1 of ‘__raw_readl’ makes pointer from integer without a cast [-Wint-conversion]

^~~~~~~~~~~
__raw_readl() on SuperH is a macro that casts the passed I/O address to
the correct type, while the implementations on most other architectures
expect to be passed the correct pointer type.
Add an explicit cast to fix this.
Note that this also gets rid of a sparse warning on SuperH:
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16: warning: incorrect type in argument 1 (different base types)
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16: expected void const volatile [noderef] <asn:2>*<noident>
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16: got unsigned int
