tty: n_gsm: add keep alive support (2023-02-16 13:50:50 +0100)

----------------------------------------------------------------
TTY/Serial driver updates for 6.3-rc1

Here is the big set of serial and tty driver updates for 6.3-rc1.

Once again, Jiri and Ilpo have done a number of core vt and tty/serial
layer cleanups that were much needed and appreciated. Other than that,
it's just a bunch of little tty/serial driver updates:
- qcom-geni-serial driver updates
- liteuart driver updates
- hvcs driver cleanups
- n_gsm updates and additions for new features
- more 8250 device support added
- fpga/dfl update and additions
- imx serial driver updates
- fsl_lpuart updates
- other tiny fixes and updates for serial drivers

All of these have been in linux-next for a while with no reported
problems.
