Subject: [PATCH] scsi: ufs: Bump supported UFS HCI version to 3.0

UFS HCI 3.0 versions are being used in Qcom SM8250 based boards. Hence,
adding it to the list of supported versions.

I don't have the exact information of the additional registers supported
in version 3.0. Hence the change just adds 0x300 to the list of supported
versions to remove the below warning:

"ufshcd-qcom 1d84000.ufshc: invalid UFS version 0x300"
