This next set of patches to drivers/tty fixes up more drivers that would perhaps appear modular when looking at the code, but are controlled by a bool Kconfig. We make sure they don't look modular and get rid of module related code in the drivers that would never be used.
The one common thread here for all the patches is that we also scrap the .remove functions which would only be used for module unload (impossible) and driver unbind. For the drivers here, there doesn't seem to be a sensible unbind use case (vs. e.g. a multiport PCI ethernet driver where one port is unbound and passed through to a kvm guest or similar). Hence we just explicitly disallow any driver unbind operations to help prevent root from doing something illogical to the machine that they could have done previously. We've already done this for drivers/tty/serial/mpsc.c previously. Build tested for allmodconfig on ARM64 and powerpc for tty/tty-testing.
