drm/msm/dpu: Drop unused GPIO code
The DPU has some kind of idea that it wants to be able to bring up power using GPIO lines. The struct dss_gpio is however completely unused and should this be done, it should be done using the GPIO descriptor framework rather than this API which relies on the global GPIO numberspace. Delete this code before anyone hurt themselves. The inclusion of <linux/gpio.h> was abused to get some OF and IRQ headers implicitly included into the DPU utilities, make these includes explicit and push them down into the actual implementation.
