stm32f: Disable UART receive DMA
Not sure why, but it doesn't seem to work consistently on my Spring.
Transmit works fine, but on some boots receive doesn't seem to pick up
received characters. Rather than churning Spring to fix this, just
disable receive DMA - which doesn't benefit Spring much anyway,
because it never downclocks its core to 1 MHz.
BUG=chrome-os-partner:24141
BRANCH=none
TEST=Boot Spring; typing into console works. After 'apshutdown', typing still
works (including arrow keys). Repeat 20 times. Repeat on Pit.
