mediatek: remove files and patches for Linux 5.4

All subtargets only provide files and patches for Linux 5.10 by now
so there is little use for the old Linux 5.4 stuff. Remove it.

-Subject: mtd: parsers: trx: Allow to specify brcm,trx-magic in DT
-
-Buffalo uses a different TRX magic for every device, to be able to use
-this trx parser, make it possible to specify the TRX magic in device
-tree. If no TRX magic is specified in device tree, the standard value
-will be used. This value should only be specified if a vendor chooses to
-use a non standard TRX magic.
