Subject: [PATCH] scsi: ufs: ufs-qcom: Add more rates to
 ufs_qcom_freq_to_gear_speed()

From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>

Booting up -next on SDM845 results in a number of warnings like:

ufshc: ufs_qcom_freq_to_gear_speed: Unsupported clock freq : 50000000
ufshc: ufs_qcom_freq_to_gear_speed: Unsupported clock freq : 200000000

Add the rates to the switch statement to make the check happy.

Fixes: c02fe9e222d1 ("scsi: ufs: qcom: Implement the freq_to_gear_speed() vop")
