Move SGPIO configuration and control to baseband firmware.
...
Addresses long-standing and annoying bug where SGPIO DMA channel would not disable -- and not configure cleanly next time it was needed. My theory is that the DMA channel couldn't disable until it got a request from the peripheral, and sometimes the peripheral was disabled before that last request.
Anyway, the baseband firmware should control the SGPIO, methinks, despite the impact on baseband code size.
