1. fix heap management for stm32f0xx(SRAM=8k)
2. add USART1, USART2 driver for stm32f051R8
3. fix finsh support for stm32f0x
4. fix board components initial for stm32f0x and open debug msg
5. add led driver(pc9) and test thread for stm32f0discovery board
6. add init thread for stm32f0x do components initial
7. add rcc initial for stm32f0x in rt_hw_board_init()
8. add print rcc freq information function
the console output example is:
SYSCLK_Frequency is 48000000HZ
PCLK_Frequency is 48000000HZ
HCLK_Frequency is 48000000HZ
CECCLK_Frequency is 32786HZ
ADCCLK_Frequency is 14000000HZ
USART1CLK_Frequency is 48000000HZ
I2C1CLK_Frequency is 8000000HZ
SystemCoreClock is 48000000HZ
