* implement rfid_reader_{get,set}opt()

* move get/set environment and get firmware api version to reader_{get,set}opt()
* merge rc632 power_up and power_down functions in new power function
* merge rc632 layer 2 protocol init functions into one
* rename parameters of rfid_layer2_{get,set}opt()
* move rf_power() function of reader to new setopt() interface
* merge reader layer 2 protocol init functiosn into one
* move most of the iso15693 anticol implementation from asic into layer2 code
* make most iso15693 parameters configurable via layer2_{get,set}opt()
* implement AFI for iso15693 inventory request
* introduce new generic 'rc632 asic based reader' functions
* use those functions from openpcd, cm5121 and spidev readers
* use new register initialization script data structure for rc632 init functions
* TODO update
