ARM: pxa/hx4700: Remove unwanted request for GPIO105

GPIO105 (nIR_ON) is requested twice: first in gpio_request_array(), then in
pxa_irda_probe(). Consequently the second request fails with EBUSY:

pxa2xx-ir: probe of pxa2xx-ir failed with error -16

This patch removes the first request, allowing pxa_irda_probe() to succeed.
