Char / Misc driver updates for 5.14-rc1

Here is the big set of char / misc and other driver subsystem updates
 for 5.14-rc1.  Included in here are:
 	- habanna driver updates
 	- fsl-mc driver updates
 	- comedi driver updates
 	- fpga driver updates
 	- extcon driver updates
 	- interconnect driver updates
 	- mei driver updates
 	- nvmem driver updates
 	- phy driver updates
 	- pnp driver updates
 	- soundwire driver updates
 	- lots of other tiny driver updates for char and misc drivers
 
 This is looking more and more like the "various driver subsystems mushed
 together" tree...
 
 All of these have been in linux-next for a while with no reported
 issues.
