m68k: apollo: Replace set but not used variable by READ_ONCE()
When building with W=1:
arch/m68k/apollo/config.c: In function ‘dn_timer_int’:
arch/m68k/apollo/config.c:171:32: warning: variable ‘x’ set but not used [-Wunused-but-set-variable]
149 | volatile unsigned char x;
| ^
Fix this by using READ_ONCE(), and removing the variable.
As READ_ONCE() casts to volatile internally, remove the existing cast.
Deduplicate the remaining casts by introducing an intermediary.
