For system controller RTC, as it belongs SC_R_SYSTEM,
and SC_R_SYSTEM is assigned in ARM-Trusted-Firmware,
so here needs to use SIP to trap into ATF to do set
time, or system controller firmware will return
error since linux kernel does NOT own this system
resource.

Add i.MX system controller RTC driver. The RTC
is controlled by system controller, and kernel RTC
driver needs to communicate with system controller
via SC firmware API.
