x300: add front-panel GPIO source control
Adds a ZPU register to control the FP GPIO source. These are 2bits
per GPIO pin, totalling 24 bits. 0 corresponds to RF-A, 1 corresponds
to RF-B. The following Python code will control the upper 6 bits of the
front-panel GPIO from the B-side radio on an X300:
>>> import uhd
>>> U = uhd.usrp.MultiUSRP("type=x300")
>>> U.get_gpio_src_banks()
['FP0']
>>> U.get_gpio_src("FP0")
['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA',
'RFA', 'RFA']
>>> U.set_gpio_src("FP0", ['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA',
'RFB', 'RFB', 'RFB', 'RFB', 'RFB', 'RFB'])
>>> U.get_gpio_src("FP0")
['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFB', 'RFB', 'RFB', 'RFB',
'RFB', 'RFB']
>>> # Make all GPIOs outputs:
>>> U.set_gpio_attr("FP0A", "DDR", 0xFFF)
>>> U.set_gpio_attr("FP0B", "DDR", 0xFFF)
>>> # Control all GPIOs from software (not ATR):
>>> U.set_gpio_attr("FP0A", "CTRL", 0x000)
>>> U.set_gpio_attr("FP0B", "CTRL", 0x000)
>>> # Bottom 3 pins go high from radio A
>>> U.set_gpio_attr("FP0A", "OUT", 0x007)
>>> # Top 3 pins go high from radio B
>>> U.set_gpio_attr("FP0B", "OUT", 0xE00)
Amends the gpio.cpp example to allow switching the source.
