0fd3d91152 dm: Use access methods for dev/uclass private data
Most drivers use these access methods but a few do not. Update them.

In some cases the access is not permitted, so mark those with a FIXME tag
for the maintainer to check.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

35b8b92c85 drivers: mux: mmio-based syscon mux controller
This adds a driver for mmio-based syscon multiplexers controlled by
bitfields in a syscon register range.
This is heavily based on the linux mmio-mux driver.

90a979d788 dm: board: complete the initialization of the muxes in initr_dm()
This will probe the multiplexer devices that have a "u-boot,mux-autoprobe"
property. As a consequence they will be put in their idle state.
