clk: qcom: gcc-sm8550: Use floor ops for SDCC RCGs

In line with commit a27ac3806b0a ("clk: qcom: gcc-sm8450: Use floor ops
for SDCC RCGs") done to fix issues with overclocked SD cards on SM8450
powered boards set floor clock operations for SDCC RCGs on SM8550.

This change fixes initialization of some SD cards, where the problem
is manifested by the SDHC driver:

    mmc0: Card appears overclocked; req 50000000 Hz, actual 100000000 Hz
    mmc0: error -110 whilst initialising SD card
