* introduce pe_enabled, which (will) indicate whether the radar
detection stuff is enabled or not. Right now it's incorrectly
set, based on something previously written. I'll sort it out
later.
* Don't set HAL_PHYERR_PARAM_ENABLE in pe_relstep to say whether
radar detection is on.
* Return whether blockradar, fir128 and enmaxrssi is enabled.
* Change some of the phyerr params to be integers rather than
HAL_BOOL so they can be set to the NOPARAM value when the
setup function is called. This is in line with other radar
parameters.
* Add new configuration parameters for fir128, blockradar and
enmaxrssi, rather than defaulting to off, on and on respectively.
