Also redefine GPIOs even after WDS canned config.
Also enable more ints.

lots of small misc changes
conditional storage of int status
custom irq setting
cut long lines and add {}
add bit definitions for int definition
upper half: manage read timeout

properly set the data rate
preliminary tx power setting, uncalibrated
TX_NCO_MODE definitions
support for CW modulation (module behave as a signal generator)

implement get_chip_status and use it to detect command errors

add fifo read and write commands
add comments, add a function to set a single byte property
add bits for global config property and fast response register options

also fix upper half ioctl
