ARM: OMAP2+: CM: prepare for use of cm_ll_data function pointers
There are several CM operations which behave similarly across OMAP2+
SoCs, but which have slight differences in their underlying
implementations.
This patch creates the support code for this function pointer
registration process. No function pointers are included yet, but a
subsequent patch will create these for the module IDLEST registers.
This patch allows other code to use CM-provided data and operations
without needing to know which SoC is currently in use. A further
description of the concept is provided in the patch entitled
"ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointers".
