staging: wfx: setup initial chip configuration
A few tasks remain to be done in order to finish chip initial
configuration:
- configure chip to use multi-tx confirmation (speed up data
transfer)
- configure chip to use wake-up feature (save power consumption
during runtime)
- set hardware configuration (clocks, RF, pinout, etc...) using a
Platform Data Set (PDS) file
On release, driver completely shutdown the chip to save power
consumption.
Documentation about PDS and PDS data for sample boards are available
here[1]. One day, PDS data may find a place in device tree but,
currently, PDS is too much linked with firmware to allowing that.
This patch also add "send_pds" file in debugfs to be able to dynamically
change PDS (only for debug, of course).
