mei: hbm: add capabilities message
The new capabilities command in HBM version 2.2 allows
performing capabilities handshake between the firmware
and the host driver. The driver requests a capability
by setting the appropriate bit in 24bit wide bitmask and
the fw responses with the bit set providing the requested
capability is supported.
