Add code to control MAX2837 B1 through B7 from Jellybean. Another feeble attempt to control DC bias.

Add code to control RXHP pin on MAX2837 (Jellybean only). I was hoping this would control the baseband DC offset problem, but no, it doesn't seem to help at all.

Add USB control of LPF baseband filter.
...
Add max2837_set_lpf_bandwidth() function to choose available LPF filter bandwidth based on bandwidth in Hz.
Change configuration of MAX2837 to set LPF_EN and FT at max2837_setup(), not in max2837_rx() or max2837_tx() (which was overriding prior filter configuration).

Use new ssp_transfer() function instead of ssp_write().
...
Implement max2837_spi_read().

Now that RxVGA gain control is working correctly, gain needs to be backed WAAAY off to get a usable capture in a fairly noisy 2.4GHz environment.

Pulled SSP1 configuration for MAX2837 into hackrf_core. Added SSP1 configuration for MAX5864. Added #defines for manipulating CS of both MAX parts. Changed a couple of #define names to be consistent with other names. Added explicit manipulation of MAX2837 CS via GPIO.

setting those TX registers is unnecessary, we just have to set the TXENABLE pin

max2837: updates
...
- band setting in set_frequency()
- rework init() to copy default settings from static data
- tweak some awkward naming in reg defs to be equally awkward but consistent
