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 1/2] spi: make spi-max-frequency optional
-
-We only need a spi-max-frequency when we specifically request a
-spi frequency lower than the max speed of spi host.
-This property is already documented as optional property and current
-host drivers are implemented to operate at highest speed possible
-when spi->max_speed_hz is 0.
-This patch makes spi-max-frequency an optional property so that
-we could just omit it to use max controller speed.
