gpio/omap: Add DT support to GPIO driver

Browse source

Adapt the GPIO driver to retrieve information from a DT file.

Allocate the irq_base dynamically and rename bank->virtual_irq_start
to bank->irq_base.
Change irq_base type to int instead of u16 to match irq_alloc_descs
output.

Add documentation for GPIO properties specific to OMAP.
