Subject: [PATCH] gpio: blzp1600: drop dependency on OF headers

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

Use the generic boolean device property getter instead of the
OF-specific variant. This allows us to stop pulling in linux/of.h. While
at it: drop the of_irq.h inclusion as none of its symbols are used in
this driver.
