at86rf2xx: Set page 2 by default on AT86RF212B

Browse Source 
Page 2 is O-QPSK 100 kbit/s or 250 kbit/s, which matches the bandwidth
provided in the 2.4 GHz band, at the cost of receiver sensitivity. The
previous default, page 0, provides only 20 kbit/s in channel 0, and
40 kbit/s in channels 1-10, and should be used in specific applications
where the radio environment requires the maximum receiver sensitivity
and noise resilience.
