kernel.h defines READ and WRITE, so rename the SH math-emu macros
to MREAD and MWRITE.

Fixes these warnings:

../arch/sh/math-emu/math.c:54: warning: "WRITE" redefined
   54 | #define WRITE(d,a) ({if(put_user(d, (typeof (d) __user *)a)) return -EFAULT;})
In file included from ../arch/sh/math-emu/math.c:10:
../include/linux/kernel.h:37: note: this is the location of the previous definition
   37 | #define WRITE   1
../arch/sh/math-emu/math.c:55: warning: "READ" redefined
   55 | #define READ(d,a) ({if(get_user(d, (typeof (d) __user *)a)) return -EFAULT;})
In file included from ../arch/sh/math-emu/math.c:10:
../include/linux/kernel.h:36: note: this is the location of the previous definition
   36 | #define READ   0
