i2s0 and i2s1 are paired input/output connected to the same codec and

The i2sN-share properties were never documented in the dt-binding and
thus shouldn't be used. Now that the ASoC machine drivers are setting
the I2S clock sharing internally, these properties are no longer needed,
so remove them.

When the DT node has "switches" available, register a Type-C mode-switch
for each listed "switch". This allows the driver to receive state
information about what operating mode a Type-C port and its connected
peripherals are in, as well as status information (like VDOs) related to
that state.

The callback function is currently a stub, but subsequent patches will
implement the required functionality.

Parse the "switches" node, if available, and count and store the number
of Type-C switches within it. Since we currently don't do anything with
this info, no functional changes are expected from this change.

This patch sets a foundation for the actual registering of Type-C
switches with the Type-C connector class framework.

The mfg_ref_sel clock is a mux used to switch between different "safe"
(and slower) clock sources for the GPU: this is used during MFGPLL
reconfiguration and eventually during idling at very low frequencies.

This clock getting turned off means that the GPU will occasionally be
unclocked, producing obvious consequences such as system crash or
unpredictable behavior: assigning it to the top level MFG power domain
will make sure that this stays on at all times during any operation on
the MFG domain (only GPU-related transactions).
