Subject: [PATCH v4 8/8] MIPS: Unselect ARCH_MIGHT_HAVE_PC_SERIO if MIPS_GENERIC

From: Miodrag Dinic <miodrag.dinic@...tec.com>

This effectively disables i8042 driver for MIPS_GENERIC kernel platform.
Currently, only sead-3, boston and ranchu boards are supported by the
MIPS generic kernel and none of them require this driver.
More specifically, kernel would crash if it gets enabled, because
i8042 driver would try to read from an non-existent IO register.
