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.
