gpio/omap: move bank width into struct gpio_bank 

Rather than having a file-global bank_width variable, move it into
struct gpio_bank so it can be bank-specific.   Note the bank width
is already passed per-bank via platform_data, so current code would
be incorrect if any banks had different width.
