TTY/Serial fixes for 5.10-rc3

Here are a small number of small tty and serial fixes for some reported
problems for the tty core, vt code, and some serial drivers.

They include fixes for:
	- a buggy and obsolete vt font ioctl removal
	- 8250_mtk serial baudrate runtime warnings
	- imx serial earlycon build configuration fix
	- txx9 serial driver error path cleanup issues
	- tty core fix in release_tty that can be triggered by trying to
	  bind an invalid serial port name to a speakup console device

Almost all of these have been in linux-next without any problems, the
only one that hasn't, just deletes code :)
