MIPS: pm-cps: convert smp_mb__*()
Commit 91bbefe6b0fc "arch,mips: Convert smp_mb__*()" replaced the
smp_mb__* functions with a simpler API, whilst commit 3179d37ee1ed
"MIPS: pm-cps: add PM state entry code for CPS systems" introduced
new uses of smp_mb__before_atomic_inc & smp_mb__after_clear_bit.
Replace those calls with the corresponding before & after atomic
functions of the new, simpler API in order to avoid a build failure:
arch/mips/kernel/pm-cps.c: In function 'coupled_barrier':
arch/mips/kernel/pm-cps.c:104:2: error: 'smp_mb__before_atomic_inc' is
deprecated (declared at include/linux/atomic.h:11)
[-Werror=deprecated-declarations]
arch/mips/kernel/pm-cps.c: In function 'cps_pm_enter_state':
arch/mips/kernel/pm-cps.c:161:2: error: 'smp_mb__after_clear_bit' is
deprecated (declared at include/linux/bitops.h:48)
[-Werror=deprecated-declarations]
