p54: enhance rssi->dBm database import
This patch fixes several shortcomings of the
previous implementation. Features of the
rewrite include:
* handles undocumented "0x0000" word at the
start of the frequency table.
(Affected some early? DELL 1450 USB devices
and my Symbol 5GHz miniPCI card.)
* supports more than just one reference point
per band. (Also needed for the Symbol card.)
* ships with default values in case the eeprom
data is damaged, absent or unsupported.
