serial: txx9: Add missing #include <asm/txx9/generic.h>

Browse Source 
drivers/tty/serial/serial_txx9.c:933:12: error: no previous prototype for ‘early_serial_txx9_setup’ [-Werror=missing-prototypes]
  933 | int __init early_serial_txx9_setup(struct uart_port *port)
      |            ^~~~~~~~~~~~~~~~~~~~~~~

This function is called from arch/mips/txx9/generic/setup.c, and does
have a forward declaration in arch/mips/include/asm/txx9/generic.h.

As the TXX9 serial driver does not support compile-testing, and thus can
only be built on MIPS, fix this by including the MIPS-only header file.
