MIPS: BCM47XX: Convert buttons to software nodes

Browse Source

Convert the legacy gpio-keys platform device on BCM47XX boards to
use software nodes/properties. This allows us to describe the GPIO
keys and their GPIO bindings using software nodes, so that support
for platform data can eventually be removed from the gpio-keys
driver.

Detect the active bus type (BCMA or SSB) and reference the
corresponding GPIO controller's software node (bcma_gpio_swnode or
ssb_gpio_swnode) in the button properties.
