[PATCH V4 42/62] ST SPEAr13xx: Modified static mappings

[Viresh Kumar]

From: Shiraz Hashim <shiraz.hashim at st.com>

The new static io mappings map regions in 0xE...,.... space to
0xF...,.... and those in space 0x6...,.... to 0xE...,.... range.
This is done to accomodate regions of RAS configuration registers to be
used by clock frameowrk and possibly others.
