* update hackrf submodule
* add platform_gpio.c and platform_scu.c to baseband build
-New source files required by the updated hackrf submodule.
* adapt scsi.c to updated hackrf API
-Rename struct gpio_t to struct gpio and add gpio_lpc.h include.
* adapt hackrf_core.c to updated hackrf API
- Rename struct gpio_t to struct gpio throughout
- Add platform_gpio.h, platform_scu.h, and fixed_point.h includes
- Update pin_setup() to use platform_scu() accessor instead of SCU_ macros
- Rewrite sample_rate_set() to use new fixed-point frequency API
- Update ssp_config_w25q80bv for changed struct layout
- Update si5351c and max283x function call signatures
