LM4: Support configurable host UART interface
Slippy uses UART2 instead of UART1 and so the EC needs
to be able to tolerate having the host use a different
interface. There are of course many ways to accomplish
that but this approach adds two config variables to specify
the host uart and the host uart irq.
The UART port setup is split out to allow them to be
configured separately rather than needing to be adjacent
in a for loop.
The interrupt functions were renamed (to ec and host) in
order to indicate which interface they are responsible for.
BUG=chrome-os-partner:19356
BRANCH=none
TEST=boot slippy and see host serial output
