* API HAL SPI: refactoring, split into layers, prepare ST HAL separation. API HAL SubGhz: initialize on start. Drivers: add basic cc1101 driver. Update API usage. Debug: increase max debugger port speed. Remove subghz apps. * CC1101: chip status handling. ApiHalSpi: increase SubGhz bus speed to 8mhz. F4: backport subghz initialization. * Api Hal SubGhz: rx path and frequency. CC1101: frequency control. * SubGhz Application: basic tests * SubGhz app: tone and packet test. API HAL SUBGHZ: update configs, add missing bits and pieces.
