Not all platforms use those. Let's use
platform_get_irq_byname_optional() instead platform_get_irq_byname() so
that we avoid a useless warning:
[ 1.359455] pxa-gpio d4019000.gpio: IRQ gpio0 not found
[ 1.359583] pxa-gpio d4019000.gpio: IRQ gpio1 not found

Okay, what would have really be nice in the commit message was to state _which_
platform doesn't use these, and still use pxa-gpio as their gpio driver.
Cheers.

PS: And yes, my response is late, but I'm moving house so my ping is huge
lately.
