arm: mvebu: update RTC values for PCIe memory wrappers
Update the RTC (Read Timing Control) values for PCIe memory wrappers
following an ERRATA (ERRATA# TDB). This means the PCIe accesses will
used slower memory Read Timing, to allow more efficient energy
consumption, in order to lower the minimum VDD of the memory. Will lead
to more robust memory when voltage drop occurs (VDDSEG)
The code is based on changes from Marvell's U-Boot, specifically:
