Subject: [PATCH] drivers/mrf24j40: add pseudomodules for MRF24J40MA/C/D/E

Microchip offers ready-to-use modules with the mrf24j40 chip.
All but the MRF24J40MA integrate an external PA/LNA, they also come
with an RF shield.

If the PA/LNA is not enabled, the signal off these modules is really
poor.

This adds pseudomodules so that the PA/LNA is automatically enabled
when the appropriate module is used.
