[5/9] clk: qcom: mmcc-msm8998: Set CLK_GET_RATE_NOCACHE to pixel/byte clks

Commit Message

The pixel and byte clocks rate should not be cached, as a VCO shutdown
may clear the frequency setup and this may not be set again due to the
cached rate being present.
This will also be useful when shadow clocks will be implemented in
the DSI PLL for seamless timing/resolution switch.
