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.

-/**
- * Driver for the Ubiquiti RGB LED controller (LEDBAR).
- * This Controller is based on a Holtek HT32F52241 and connected
- * via I2C.
- *
- *  - The Controller needs an enable signal set to high when
- *    performing a transaction. On the U6-LR, this is located
- *    at Pin 18 (R6902)
- *
- *  - The Pin is also printed when calling the "usetled" function
- *    contained in the ubntapp bootloader application.
