Subject: [PATCH 1/2] gpio: aspeed: Make bank names strings

From: Joel Stanley <joel@....id.au>

The Aspeed SoCs have more GPIOs than can be represented with A-Z. The
documentation uses two letter names such as AA and AB, so make the names
a three-character array in the bank struct to accommodate this.
