Subject: [PATCH v6 1/8] ARM: integrator: impd1: Use GPIO_LOOKUP() helper macro

impd1_probe() fills in the GPIO lookup table by manually populating an
array of gpiod_lookup structures.  Use the existing GPIO_LOOKUP() helper
macro instead, to relax a dependency on the gpiod_lookup structure's
member names.

While this patch is a dependency for "[PATCH v6 4/8] gpiolib: Add
support for GPIO lookup by line name", it can be applied independently.
But an Acked-by would be nice, too.
