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: [PATCH] net: dsa: mt7530: Extend device data ready for adding a
- new hardware
-
-Add a structure holding required operations for each device such as device
-initialization, PHY port read or write, a checker whether PHY interface is
-supported on a certain port, MAC port setup for either bus pad or a
-specific PHY interface.
-
-The patch is done for ready adding a new hardware MT7531, and keep the
-same setup logic of existing hardware.
