[PATCH] pmdomain: ti_sci: add CONFIG_PM_SLEEP dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Without CONFIG_PM_SLEEP, the pm_generic_suspend() function cannot be called
since it is defined to NULL:

In file included from include/uapi/linux/posix_types.h:5,

                 from drivers/pmdomain/ti/ti_sci_pm_domains.c:10:
