Add support for RGB565, RGB888 and BGR888 media bus formats.
The pixel formats for these have a different byte-order than the MIPI
bus formats, given the SHIM IP [1] unpacks them into memory as follows:
MIPI RGB888 unpacks to:
BYTE3 BYTE2 BYTE1 BYTE0
00000000 RRRRRRRR GGGGGGGG BBBBBBBB
MIPI RGB565 unpacks to:
BIT 15-11 BIT 10-5 BIT 4-0
RRRRR GGGGGG BBBBB

Since commit 1029939b37 ("media: v4l: async: Simplify async sub-device fwnode matching"),
async connections are matched using the async sub-device fwnode, not that
of the endpoint. Fix this by using the fwnode of the connection match to
find the pad.

Change the interface of power management functions in s5p_mfc_pm.c to
accept the pointer to S5P MFC device structure. instead of relying on
file-scope static variable. This makes code easier to read and modify
in case more devices are added.

Pull more bcachefs updates from Kent Overstreet:
"Some fixes, Some refactoring, some minor features:
- Assorted prep work for disk space accounting rewrite
- BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
makes our trigger context more explicit
- A few fixes to avoid excessive transaction restarts on
multithreaded workloads: fstests (in addition to ktest tests) are
now checking slowpath counters, and that's shaking out a few bugs
- Assorted tracepoint improvements
- Starting to break up bcachefs_format.h and move on disk types so
they're with the code they belong to; this will make room to start
documenting the on disk format better.
- A few minor fixes"
