Update the RF, RFGAIN, MODE, INI, and BBGAIN initialization tables

Update the RF, RFGAIN, MODE, INI, and BBGAIN initialization tables
with different versions for various ar5212 variants and add an extra
table for PCI-E devices.  This fixes support for various newer devices
(like the 1st generation MacBook, T61 variants) but it still does not
work on a number of other devices.
