Christian Lamparter e90dc8d272 apm821xx: convert to device-tree board detection
This patch converts all apm821xx devices to the device-tree
board-detection method. All instances of the legacy
boardnames (mbl,mr24,...) are converted to "vendor,device"
identifier.

The custom board-detection code in apm821xx.sh is removed as
it no longer serves any purpose.
