ARM: OMAP5: srcomp: enable slew rate compensation cells after powerup

After power-up SRCOMP cells are by-passed by default in OMAP5.
Software has to enable these SRCOMP sells.
For ES2: All 5 SRCOMP cells needs to be enabled.
For ES1: Only 4 SRCOMP cells in core power domain are enabled.
	 The 1 in wkup domain is not enabled because smart i/os
	 of wkup domain work with default compensation code.
