Fix clock edge for TX mode. TX data was completely crapped up due to skew on my Jellybean/Lemondrop board. Hopefully, this also applies to Jawbreaker. I'll recheck once I have hardware in-hand.

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).

Remove weird LDSCRIPT that isn't necessary now.
...
Change .bin generation to include only ROM-able sections.
TODO: Is there a better way to do the objcopy? It'd be great to put everything in the "rom" region into the .bin, instead of having to list out -j section for each of the sections that go to ROM.

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.

Fixed incorrect field with for MAX2837 VGAgain_SPI_EN field. For boards that have no B7:B1 connections, this could prove extra problematic...and for boards that do, but aren't driving those pins from the LPC.

Added fault handler header file, where I've defined the Cortex-M3/M4 SCB using a struct instead of a slew of #defines. This deviates from the libopencm3 method, but is superior in other ways. So, there you go. It's not in libopencm3, it's here.
...
Added example (er, "reminder") code comment about registers to look at when debugging a Hard Fault.
