[PATCH 13/24] ARM: OMAP2+: clock: add support for specific CM ops to ti_clk_ll_ops

[t-kristo@ti.com (Tero Kristo)]

Clock driver requires access to some CM API functions once the code
is being moved under the clock driver from the platform directory.
Gate type clock requires access to cm_wait_module_ready and
cm_split_idlest_reg functions, which are both used for waiting until
the module being clocked has been successfully activated. These CM
APIs are now exported through the ti_clk_ll_ops struct.
