* RFID: pull antenna down when emulating
* Rfid: fixed HID emulation by adding zero pulse every 4 bits
* Rfid: HID emulation fixed with DSP based FSK oscillator.
* Rfid: receive 125KHz clock for emulation timer from antenna and comparator
* Rfid: commented unused variable
* Firmware: rollback changes in f6.
* Add F7 target based on F6.
* F7/F6: update cube projects, apply changes to the targets, update linker scripts with correct RAM start values.
* FuriHal: RFID init routine.
