MIPS: Malta: initialise the RTC at boot
The RTC is used on Malta to estimate the clock frequency of the CPU & optionally the GIC. However the kernel previously did not initialise the RTC, instead relying upon the bootloader having done so. In order to minimise dependencies which the kernel has upon the bootloader this patch causes the kernel to initialise the RTC itself prior to making use of it.
