ddr cfg: DRAM_RESET needs 0x00020030
The old value of 0x000e0030 will cause ethernet
timeout issues on the sabrelite and possibly other
boards using the KSZ9021.
I have no explanation as to why.
But this is a correct change, the TRM will be updated
to show that 00b is the only valid setting for bits
19-18 of DRAM_RESET.
My thanks go to Liu Hui(Jason) for this information.
