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

+  *
+  * @note   Each time the core clock (HCLK) changes, this function must be called
+  *         to update SystemCoreClock variable value. Otherwise, any configuration

+  *
+  * @note   - The system frequency computed by this function is not the real
+  *           frequency in the chip. It is calculated based on the predefined
+  *           constant and the selected clock source:
+  *
+  *           - If SYSCLK source is MSI, SystemCoreClock will contain the MSI_VALUE(*)
+  *
+  *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(**)
+  *
+  *           - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(***)
+  *
+  *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(***)
+  *             or HSI_VALUE(*) or MSI_VALUE(*) multiplied/divided by the PLL factors.
+  *
+  *         (*) MSI_VALUE is a constant defined in stm32wbxx_hal.h file (default value
+  *             4 MHz) but the real value may vary depending on the variations
+  *             in voltage and temperature.
+  *
+  *         (**) HSI_VALUE is a constant defined in stm32wbxx_hal_conf.h file (default value
+  *              16 MHz) but the real value may vary depending on the variations
+  *              in voltage and temperature.
+  *
+  *         (***) HSE_VALUE is a constant defined in stm32wbxx_hal_conf.h file (default value
+  *              32 MHz), user has to ensure that HSE_VALUE is same as the real
+  *              frequency of the crystal used. Otherwise, this function may
+  *              have wrong result.
+  *
