drm/bridge: migrate bridge_chains to per-encoder file
Instead of having a single file with all bridge chains, list bridges
under a corresponding per-encoder debugfs directory.
While we are at it, also slightly improve the formatting of the bridge
data: split a single line entry into multiple lines, include the symbol
name of the bridge funcs and add the textual representation of the
bridge ops.
Example of the listing:
$ cat /sys/kernel/debug/dri/0/encoder-0/bridges
bridge[0]: dsi_mgr_bridge_funcs
type: [0] Unknown
ops: [0]
bridge[1]: lt9611uxc_bridge_funcs
type: [11] HDMI-A
OF: /soc@0/geniqup@9c0000/i2c@994000/hdmi-bridge@2b:lontium,lt9611uxc
ops: [7] detect edid hpd
