board: add configuration for stm32f103c8 "Blue Pill"
The "Blue Pill" is a popular development board with an STM32F103C8
micro controller. According to sources, it has a 128kB Flash on board
even though the option bytes only report 64kB. This patch therefore also
modifies target/stm32f1x.cfg to take an optional FLASH_SIZE variable into
account which the board file sets to 0x20000.
