scsi: ufshcd: use a macro for UFS versions

[Caleb Connolly <caleb@connolly.tech>]

When using a device with UFS > 2.1 the error "invalid UFS version" is
misleadingly printed in dmesg. There was a patch for this almost a year
ago to which this solution was suggested, lets avoid growing a list of
versions and just use a macro instead.

I've also dropped that check entirely as it seems to be more misleading
than useful, and hasn't been accurate for a long time.

I dealt with the different encoding used for UFS 1.x by converting it
to match the newer versions in ufshcd_get_ufs_version(). That means it's
possible to use comparisons for version checks, e.g.

        if (hba->ufs_version < UFSHCI_VER(3, 0))
                ...


I've tested this on a device with UFS 3.0 and a device with UFS 2.1
however I don't own any older versions to test with.
