STM32 uart Kconfig instance flags were not following
same naming scheme than other drivers (i2c, spi, ..)
Update driver to use UART_X instead of UART_STM32_PORT_X

Current configuration was choosen to avoid colliding with existing ones
for i2c and uart, but others can be used (see
drivers/pinmux/stm32/stm32_f0.h)
