jtag/adapter: Add command 'adapter gpio'

Browse Source 
Most adapters define their own commands to obtain the GPIO number and
other GPIO configuration information such as chip number, output drive
type, active high/low.

Define a general command 'adapter gpio' as replacement for the
driver-specific ones.
