[PATCH 09/11] ARM: OMAP3: PRM: add support for legacy iomapping init

[Tero Kristo]

As the legacy clock data is being moved under clock driver, the
clock data will be using the same low level infrastructure for
register accesses. This requires the clk_memmaps to be initialized
properly. This patch adds a support hook to the PRM driver to
initialize the mappings.
