Janusz Krzysztofik 9773861304 mtd: rawnand: ams-delta: Request data port GPIO resource 
Data port used by the driver is actually an OMAP MPUIO device, already
under control of gpio-omap driver.  For that reason we used to not
request the memory region of the port as that would fail because the
region is already busy.  Despite that, we are still accessing the port
by just ioremapping it and performing read/write operations.  Moreover,
we are doing that without any proteciton from other users legally
manipulating the port pins over GPIO API.

The plan is to convert the driver to access the port over GPIO consumer
API.  Before that happens, already prevent from other users accessing
the port pins by requesting an array of its GPIO descriptors.
