ramips: mt7620: export chip version and pkg
Similar to the (currently unused) mt7620_get_eco() function, introduce mt7620_get_chipver() and mt7620_get_pkg() functions to allow rt2x00 to probe for the type of WiSoC. This is ugly and probably unacceptable for upstream, however, it should help to evaluate which of those hacks are actually really needed, enumerate the possible values and label them in a more meaningful way than currently done in the vendor driver.
