TTY / Serial driver fixes for 5.13-rc4

Here are some small fixes for reported problems for tty and serial
drivers for 5.13-rc4.

They consist of:
	- 8250 bugfixes and new device support
	- lockdown security mode fixup
	- syzbot found problems fixed
	- 8250_omap fix for interrupt storm
	- revert of 8250_omap driver fix as it caused worse problem than
	  the original issue

All but the last patch have been in linux-next for a while, the last one
is a revert of a problem found in linux-next with the 8250_omap driver
change.
