p54: regulatory domain hints

Browse Source 
This patch adds a sub-routine that parses the default country eeprom entry
and forwards the obtained Alpha2 identifier to the regulatory sub-system.

Note: I dropped the p54 specific regdomain<->alpha2 conversion code for now.
But it will be added as soon as there's the common library function is ready.
