drivers/tty: make pty.c slightly more explicitly non-modular
The Kconfig currently controlling compilation of this code is: drivers/tty/Kconfig:config LEGACY_PTYS drivers/tty/Kconfig: bool "Legacy (BSD) PTY support" ...and: drivers/tty/Kconfig:config UNIX98_PTYS drivers/tty/Kconfig: bool "Unix98 PTY support" if EXPERT combined with this: obj-$(CONFIG_LEGACY_PTYS) += pty.o obj-$(CONFIG_UNIX98_PTYS) += pty.o ...meaning that it currently is not being built as a module by anyone. Lets remove the traces of modularity we can so that when reading the driver there is less 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 don't delete the module.h include since other parts of the file are using content from there.
