In adc_calibrate_async() we should only set the ADCAL bit and leave the rest alone.
While in the past there were only "rs" bits in this register, this is no
longer the case.

Generate doc root doxygenlayout file, as well as devices stuff, based on main
Makefile $(TARGETS) and template files. Avoids painfull sync/merge of 20 files+
when adding a new device.
bonus : allow to build only one device doc easily (make TARGETS=stm32f0 doc)
regression: we currently loose device "fancy" naming as device name is
guessed (toUpper()..) from folder name.
GD32F1X0 (X can be 3, 5, 7 and 9) is a series of Cortex-M3 MCUs by
GigaDevice, which features pin-to-pin package compatibility with
STM32F030 MCU line. F150 adds USB support to F130, and F170/F190 adds
CAN support.
Currently the code mainly targets GD32F130 and F150 chips. Some register
are different between F130/150 and F170/190, just like the difference
between STM32F1 Performance line and Connectivity line.
From the perspective of registers and memory map, GD32F1X0 seems like a
mixture between STM32F1 and STM32F0 (because it is designed to be
pin-to-pin compatible with F0, but with Cortex-M3 like F1). A bunch of
code are shared between STM32 and GD32, and these code are specially
processed to include the GD32 headers instead of STM32 headers when meet
GD32F1X0.

gd32/rcc.[ch] are forks of stm32f1/rcc
gd32/flash.[ch] are forks of stm32f0/flash
No attempts at deduplicating this have been done at this stage. We can
see where they move in the future.
Make exti_get_flag_status and exti_reset_request use EXTI_RPR and EXTI_FPR if present instead of EXTI_PR.
This is less precise than offered by the RPR/FPR registers, but makes
for a consistent experience in the common API.

EXTICR on stm32g0 is in exti registers range. Previous chips used to have that
gpio port exti mux configuration accessible via AFIO_EXTICR or SYSCFG_EXTICR.
Also, the new chip now use 8 bits coded value instead of previously 4 for the
extcr mux selection value (see AFIO/SYSCFG/EXTI_EXTICR_FIELDSIZE)
Let's define two helpers: EXTICR_SELECTION_REG (to get proper AFIO/SYSCFG/
EXTI_EXTICR register) and EXTICR_SELECTION_FIELDSIZE (to get proper AFIO/SYSCFG/
EXTI_EXTICR_FIELDSIZE value), and use it them exti_select_source to determine
exticr mux selection bits shift and mask.
While on all current chips, exticr gpio port mux selection is coded on 4 bits,
stm32g0 EXTI_EXTICR register uses 8 bits. Align all exti header to reference
that value (was previously defined for f0 as SYCFG_EXTICR_SKIP)
flash_unlock_acr allows to unlock RUN_PD bit from FLASH_ACR register. Relock is done automatically
when writing 0 to RUN_PD, so no flash_lock_acr method.
