ARM: OMAP2+: Add CFI type for omap4_finish_suspend

Browse Source 
With CONFIG_CFI enabled, OMAP4 can trap in omap4_enter_lowpower()
because omap_pm_ops.finish_suspend points directly to the assembly
routine omap4_finish_suspend, which lacks the expected KCFI type
metadata.

Annotate omap4_finish_suspend with SYM_TYPED_FUNC_START so the assembly
routine carries the KCFI type metadata.
