[PATCH 6/6] ARM: OMAP2+: hwmod: use init-time function pointer for _init_clkdm

[Kevin Hilman]

Rather than use runtime cpu_is* checking inside _init_clkdm, initialize
SoC specific function pointer at init time.

Note that initializing the function pointer oh->init_clkdm pointer
must be done before _init_clocks() is called because it is used there.
