Subject: [PATCH] regulator: core: Handle PM_SUSPEND_TO_IDLE suspend_state_t

The regulator framework is used on x86 in some cases now and x86 has
a PM_SUSPEND_TO_IDLE suspend_state_t, treat this as PM_SUSPEND_STANDBY,
this fixes these errors on resume:

dpm_run_callback(): regulator_resume_early+0x0/0x60 returns -22
PM: Device regulator.0 failed to resume early: error -22
