MIPS: MTX-1: Request button GPIO before setting its direction

This patch fixes the following warning at boot time:
WARNING: at drivers/gpio/gpiolib.c:83 0x8021d5e0()
autorequest GPIO-207

Call Trace:[<8011e0ec>] 0x8011e0ec
[<80110a28>] 0x80110a28
[<80110a28>] 0x80110a28
[..snip..]

The current code does not request the GPIO and attempts
to set its direction, which is a violation of the GPIO API.
This patch also unhardcode the GPIO we request and use
the one we defined in the button driver.
