[U-Boot] [PATCH 2/2] armv8: ls1012a: Update Refresh cycle for DDR

[Prabhakar Kushwaha]

Refresh cycle value must be selected based on the frequency
of DDR. tREFI = 7.8 us as per JEDEC. The value for MDREF[REF_CNT]
should be based on round up (tREFI/tCK) formula. For 500MHz, mdref
value should be 0x0f3c8000.
