[OpenWrt-Devel] [PATCH 7/8] staging: mt7621-gpio: use MTK_BANK_WIDTH instead of magic number

[Rosen Penev]

From: Sergio Paracuellos <sergio.paracuellos at gmail.com>

There are some places where magic number '32' is being used to get
the gpio bank. There already exist a definition MTK_BANK_WIDTH
with this value, so just use it instead.
