ARM: 6649/1: omap: use fncpy to copy the PM code functions to SRAM
The new fncpy API is better suited* for copying some
code to SRAM at runtime. This patch changes the ad-hoc
code to the more generic fncpy API.
*: 1. fncpy ensures that the thumb mode bit is propagated,
2. fncpy provides the security of type safety between the
original function and the sram function pointer.
Tested OK on OMAP3 in low power modes (RET/OFF)
using omap2plus_defconfig with !CONFIG_THUMB2_KERNEL.
Compile tested on OMAP1/2 using omap1_defconfig.
Boot tested on OMAP1 & OMAP2
Tested OK with suspend/resume on OMAP2420/n810
Boots fine on osk5912 and n800
