On the A31s the RTC is by default secured. Thus when u-boot
loads the kernel in non-secure world, the RTC is unavailable. The
SoC has a TrustZone Protection Controller, which can be used to
enable non-secure access to the RTC.
On the A31 the TZPC doesn't seem to do anything, i.e. changes to
its register contents do not affect access to the RTC.
