ieee802154: remove fakehard driver 

This patch removes the not functional fakehard driver. We don't support
HardMAC 802.15.4 drivers right now.

Say Y here to enable the fake driver that serves as an example
of HardMAC device driver.
This driver can also be built as a module. To do so say M here.
The module will be called 'fakehard'.
