Subject: [PATCH] regulator: mcp16502: Use #ifdef CONFIG_PM_SLEEP around mcp16502_suspend/resume_noirq

mcp16502_suspend/resume_noirq is only used by SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
when CONFIG_PM_SLEEP is defined.
So use #ifdef CONFIG_PM_SLEEP instead CONFIG_SUSPEND guard.

This patch replaces below patch I sent today.
regulator: mcp16502: Fix build error when !CONFIG_SUSPEND && CONFIG_PM_SLEEP
Changed the subject line because after commit 308144ce8e51 ("regulator: mcp16502: code cleanup")
it's not related to build error now.
