[v3,0/1] Remove support for legacy UFS

Message

UFS1.0 and UFS1.1, published in the early 2010s, were more of a proof of
concept rather than a mature functional spec. Toshiba was the only
device manufacturer with the most accomplished phy team to come up with
a small UFS1.0 device. Alas, there were no commercial platforms it can
be paired with. Even UFS2.0 that was published in 2013, didn't really
make it to the market: too moot to take effect. It's not until UFS2.1
that was published in 2016, were a myriad of devices and platforms
flooded the market. Designated to mobile devices, dictates a rapid short
lives for those platforms. Hence, we can safely remove those pre-UFS2.0
pieces of code.

Changes from v2:
 - leave UFSHCI2.0 out of this change (Bart).

Changes from v1:
 - remove ufshcd_get_local_unipro_ver which practically mean squashing
   patch 1 & 2 into a single patch (Christoph)
 - restore an if clause to avoid functional change in
   ufshcd_compl_one_cqe (Bart)
