[PATCH v2 1/5] MIPS: jz4740: remove broken irq_to_gpio() call

[Arnd Bergmann <arnd@xxxxxxxx>]

gpiolib has removed the irq_to_gpio() API several years ago,
but the global header still provided a non-working stub.

With a MIPS-wide change to use the generic header file, the jz4740
platform is now using the wrong stub implementation of irq_to_gpio(),
which cannot work.

This uses an open-coded implementation in the only line it
is used in.
