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". Signed-off-by: Paul Walmsley <paul@pwsan.com>
