sh: clkfwk: remove r8/r16/r32
SH will get below warning
${LINUX}/drivers/sh/clk/cpg.c: In function 'r8':
${LINUX}/drivers/sh/clk/cpg.c:41:17: warning: passing argument 1 of 'ioread8'
discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
return ioread8(addr);
^~~~
In file included from ${LINUX}/arch/sh/include/asm/io.h:21,
from ${LINUX}/include/linux/io.h:13,
from ${LINUX}/drivers/sh/clk/cpg.c:14:
${LINUX}/include/asm-generic/iomap.h:29:29: note: expected 'void *' but
argument is of type 'const void *'
extern unsigned int ioread8(void __iomem *);
^~~~~~~~~~~~~~
We don't need "const" for r8/r16/r32. And we don't need r8/r16/r32
themselvs. This patch cleanup these.
