Firmware, Bootloader: add f3 target. (#215)
* Firmware, Bootloader: add f3 target. Refactor code to be portable across targets.
* Firmware: remove bkpt
* Makefile: debug agent. Debug: f3 platform throw openocd.
* freertos-openocd helper
* separate hal resources
* return of input_dump app
* using hew target resources abstration layer for backlight and blink
* dirty hack for input driver, f3 has no charging pin
* worked input interrupts
* working display
* F3: switch to 32mHz resonator
* F3: configure SD_CS pin
* NFC: port to F3.
* fat uart app
* sd card hal api
* separate CC1101 spi config
* faster spi gpio for sd card
* Assets: disable LFS
* Cube: disable css on LSE
* Input: format code
* Make: add bootloader source code to formatting rule
* F3: enable rf by default, adjust clock settings, map all pins where they should be.
* libs for coreglitch_demo_0
* nvic priority
* bus clocks all to 64
* lf-rfid timer and pin
* irda
* ir rx setup
* tim2 irq handler
* Makefile: environment aware mkdir
* Makefile, Irukagotchi: commit seq number.
* split falling and rising ir rx events
* Makefile: proper git branch detect on old git. Firmware: api fix.
* fix irda
* Makefile,Irukagotchi: date timestamp.
* NFC: adjust SPI speed
* Irukagotchi: format code
* Make: add blackmagic debug in host mode
* Makefile: detach blackmagic from terminal signals
* Makefile,Irukagotchi: stamp target
* add F3 bootloader/firmware to CI
