Enable Marvell gpio driver to work with many controllers

Browse Source 
This patch moves all global data structures into mv_gpio_softc,
and puts device_t parameter to functions calls everywhere where needed.
As a result, we can create multiple driver instances.

Removed names in function declaration to keep style.
