clk: msm: Add the CLKFLAG_NO_RATE_CACHE flag for MM clocks on MSM COBALT

The clock driver by default returns immediately if a set_rate()
request is made for a clock with a frequency that matches the
SW frequency state. This is an optimization to avoid performing
unnecessary clock configuration updates.
Due to a HW limitation of the multimedia block on MSM COBALT,
the clock sources or RCGs can end up running at XO frequency
after a multimedia power collapse. In order to avoid this,
have the multimedia clients call set_rate() prior to enabling
their clocks. In addition, add the CLKFLAG_NO_RATE_CACHE flag
to the multimedia clocks to remove the above mentioned set_rate()
optimization and re-configure the clock source for every rate
request, regardless of what rate the RCG is already configured to.
