drm/dsi: add helpers for DSI compression mode and PPS packets
Add helper functions for sending the DSI compression mode and picture
parameter set data type packets. For the time being, limit the support
to using VESA DSC 1.1 and the default PPS. This may need updating if the
need arises for proprietary compression or non-default PPS, however keep
it simple for starters.
Rename picture parameter set (it's a long packet, not a long write) and
compression mode (it's not a DCS command) enumerations according to the
DSI specification. Order the types according to the spec. Use tabs
instead of spaces for indentation. Use all lower case for hex.

Pull btrfs fixes from David Sterba:
"A bunch of fixes that accumulated in recent weeks, mostly material for
stable.
Summary:
- fix for regression from 5.3 that prevents to use balance convert
with single profile
- qgroup fixes: rescan race, accounting leak with multiple writers,
potential leak after io failure recovery
- fix for use after free in relocation (reported by KASAN)
- other error handling fixups"
