drivers/tty: make hvc/hvc_vio.c explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/tty/hvc/Kconfig:config HVC_CONSOLE
drivers/tty/hvc/Kconfig: bool "pSeries Hypervisor Virtual Console support"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
We don't replace module.h with init.h since the file already has that.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
