[PATCH v1] gpio: aggregator: Use compound literal from the header

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

Instead of doing it in place, convert GPIO_LOOKUP_IDX() and GPIO_HOG()
to be compund literals that's allow to use them as rvalue in assignments.

Due to above conversion, use compound literal from the header
in the gpio-aggregator.c.
