34XX: Suspend: Use same naming convention in sleep34xx.S as in sleep24XX.S

34XX: Suspend: Use same naming convention in sleep34xx.S as in sleep24XX.S

Change omap34xx_suspend to omap34xx_cpu_suspend and
omap34xx_suspend_sz to omap34xx_cpu_suspend_sz.

Do not use PRM_BASE in sleep34xx.S because it is not defined in
linux-omap tree.

Use OMAP343X_SDRC_BASE in sleep34xx.S instead of SDRC_BASE.

Convert all IO_ADDRESS style definitions to OMAP34XX_PRM_REGADDR style
definitions.

Add omap34xx_cpu_suspend and omap34xx_cpu_suspend_sz to
include/asm-arm/arch-omap/pm.h

Do necessary modifications to be able to use arch/arm/mach-omap2/prm.h
and include/asm-arm/arch-omap/control.h ins asm files.
