The Blue Pill board is typically fitted with a STM32F103C8T6, but
reports online seem to indicate that it sometimes can come with its
bigger sibling the STM32F103C8TB as is the case with my board.
This patch adds support for all low- to medium-density STM32F103
devices. All of these devices have their flash divided in 1 KB pages, up
to 128 KB. The high-density and connectivity line of devices, sometimes
called XL devices, use 2 KB pages and are not supported.
Similar to the STM32F4 support, the code will spin up the PLL for
maximum speed during init and turn it off just before booting the
application. the maxium speed is 72 MHz.
