[PATCH v2 0/9] AM64: Add SERDES bindings and driver support

AM64 uses the same SERDES as in J7200, however AM642 EVM doesn't
have a clock generator (unlike J7200 base board). Here the clock from
the SERDES has to be routed to the PCIE connector. This series adds
support to drive reference clock output from SERDES and also adds
SERDES (torrent) and SERDES wrapper (WIZ) bindings.

v1 of the patch series can be found @ [1]
Changes from v1:
*) Model the internal clocks without device tree input (Add #clock-cells
to SERDES DT nodes for getting a reference to the clock using index
to phandle). This is in accordance with comment given by Rob [2].
However the existing method to model clocks from device tree is not
removed to support upstreamed device tree.
*) Included a patch to fix modifying static data by instance specific
initializations.
*) Added a fix to delete "clk_div_sel" clk provider during cleanup
