Icenowy Zheng 330d5fd5be gd32: add new chip series f1x0
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.

Reviewed-by: Karl Palsson <karlp@tweak.net.au>
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.
