[PATCH 2/7] OMAP2+: use global values for the SRAM PA addresses

[jean.pihet at newoldbits.com]

From: Jean Pihet <j-pihet at ti.com>

The SRAM PA addresses are locally defined and used in both the
SRAM management code and the idle sleep code.
A global macro defines the values at a centralized place, for
easier maintenance.

Tested on N900 and Beagleboard with full RET and OFF modes,
using cpuidle and suspend.
