[riot-notifications] [RIOT] cpu: make msp430fxyz use uart stdio (#3924)

[Kaspar Schleiser]

msp430fxyz used an ugly-hacked uart_stdio replacement as it was not fast enough to handle bytewise isr-to-thread transfer using ringbuffer at 115kbaud.

Using the improved thread-safe ringbuffer (which avoids interrupt disabling), the msp easily handles higher speeds.

Depends on #3932.
