No functional change. In order to have a single header file for all
Cadence SERDES move phy-cadence-torrent.h to phy-cadence.h. This is
in preparation for adding Cadence Sierra SERDES specific macros.

Instead of having separate structure members for each input clock, add
an array for the input clocks within "struct cdns_sierra_phy". This is
in preparation for adding more input clocks required for supporting
additional clock combination.

commit 44d30d622821 ("phy: cadence: Add driver for Sierra PHY") enabled
the clock in probe and failed to disable in remove callback. Add missing
clk_disable_unprepare() in cdns_sierra_phy_remove().

No functional change. Since the reset controls obtained in
Sierra is exclusively used by the Sierra device, use
exclusive reset control request API calls.

Ideally all PHY dt nodes should have node name as "phy", however

Model the mux clocks without device tree input for AM64x SoC. Don't
remove the earlier design since DT nodes for J7200 and J721e are already
