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

- 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
