[PATCH v2] gpio: mt7621: Switch to use platform_get_irq() function

[Sergio Paracuellos <sergio.paracuellos@xxxxxxxxx>]

Mt7621 SoC GPIO driver is a platform driver so we can directly use
'platform_get_irq' instead of 'irq_of_parse_and_map'.

Tested-by: Arınç ÜNAL <arinc.unal@xxxxxxxxxx>

Change in v2:
- Make independent PATCH since this must go to next branch.
