controller: use eMediaTypeGroup to check for wireless interfaces

eMediaTypeGroup is defined as the MSB of the eMediaType, according to Table 6-12—Media type (intfType) found in IEEE 1905.1a standard. Instead of using minimum and maximum values of eMediaType to check for wireless interfaces, use the value of eMediaTypeGroup. Resulting code is easier to maintain and while we are at it, we also include the newly created IEEE_802_11AX value. Signed-off-by: Mario Maz <[email protected]>
