scsi: ufs: core: Fix bRefClkFreq write failure in HS-LSS mode
According to the UFS spec, the bRefClkFreq attribute can only be written
when both sub-links are in LS-MODE. However, in HS LSS mode with
resetmode = HS_MODE, if the UFS device's default bRefClkFreq value
differs from the host controller's dev_ref_clk_freq setting, the write
operation will fail.
To fix this issue, introduce ufshcd_get_op_mode() function to detect the
current link operational mode. Call ufshcd_set_dev_ref_clk() only when
both sub-links are in LS-MODE to ensure the attribute can be written
successfully.
