LoongArch: Add __percpu annotation for __percpu_read()/__percpu_write()
When build kernel with C=1, we get:
arch/loongarch/kernel/process.c:234:46: warning: incorrect type in argument 1 (different address spaces)
arch/loongarch/kernel/process.c:234:46: expected void *ptr
arch/loongarch/kernel/process.c:234:46: got unsigned long [noderef] __percpu *

Add __percpu annotation for __percpu_read()/__percpu_write() can avoid
such warnings. __percpu_xchg() and other functions don't need annotation
because their wrapper, i.e. _pcp_protect(), already suppresses warnings.
Also adjust the indentations in this file.
