This series goal is to adapt the Mediatek UFS dt-bindings changes
done by "MediaTek UFS Cleanup and MT8196 Enablement" series ([1])
The patches were present in the v10 revision of the series ([2])
but it was requested to be sent in a separate series. The first patch
was also modified to add a valid OPP table rather than simply dropping
the freq-table-hz array to fix an issue detected on this patch by
Sashiko ([3]) during [2] review.
The series is based on linux-next kernel tree (tag: next-20260901) and
depend on [1] with v11 or later.

The MT8195 UFS host controller dt bindings now describe several extra
required clocks that were previously missing from clock description
and deprecates the freq-table-hz property use in favour of
operating-points-v2 instead.
So, add in ufshci node the rx_symbol clocks in clock list and replace
freq-table-hz property by operating-points-v2 one with a valid OPP
table.
Also reorder properties in node.

...but obviously I need the bindings bindings to get picked before being able to
do anything here.
