clk: qcom: gcc-kona: remove FORCE_ENABLE_RCG flag from UFS clocks

Remove the FORCE_ENABLE_RCG flag from all gcc_ufs_* clocks.
This flag is used to force an RCG to stay enabled even if all
downstream branch clocks are disabled and no hardware enable
signals are asserted.  This configuration is not required for
UFS clocks.

At the same time specify the HW_CLK_CTRL_MODE flag for gcc_ufs_*
RCG clocks.  This ensures that that the rate of the clocks can
be changed safely even if the hardware enable signal from their
branch clocks is toggling.
