USI/USCI/USART SPI implementation seems not working correctly #23

I confirmed that at least USCI SPI implementation doesn't work and I'm afraid USI and USART don't work either. The BitBang SPI implementation still works fine.

I'm guessing that the issue is caused by clocking difference than tinyos-prod. I'm planning to revise the clocking code as close as tinyos-prod to solve this issue.

Confirmed that USI SPI implemenation works fine.

Confirmed that USCI SPI implementation for f2xxx works fine. Though USCI SPI implementation for g2xxx has issue on P1SEL2, that register isn't exist on f2xxx.

Confirmed pull request #30 fixes USCI A0/B0 SPI on MSP430G2553.

Remaining issues are MSP430F1232/USART0 and MSP430F1611/USART0,1.

I haven't confirmed but this commit probably fixes the remaining issue related to MSP430F1232/MSP430F1611.
