Add the 'dmac_type' key element to supported key blocks and make use of
it to match on layer 2 miss.

This is a two bits key in hardware with the following values:
00b - Known multicast.
01b - Broadcast.
10b - Known unicast.
11b - Unknown unicast or unregistered multicast.

When 'l2_miss' is set we need to match on 01b or 11b. Therefore, only
match on the LSB in order to differentiate between both cases of
'l2_miss'.

Tested on Spectrum-{1,2,3,4}.
