This looks like a really nice improvement!

I'd use early returns here to clean this up a bit:
if (hba->quirks & UFSHCD_QUIRK_BROKEN_UFS_HCI_VERSION)
ufshci_ver = ufshcd_vops_get_ufs_hci_version(hba);
...
ufshci_ver = ufshcd_readl(hba, REG_UFS_VERSION);
if (ufshci_ver & 0x00010000)
return UFSHCI_VER(1, ufshci_ver & 0x00000100);
return ufshci_ver;

This needs braces around major and minor. Or better just convert it
to an inline function (and use a lower case name).
