bde8eb35ae x86, galileo: Fix UART system call authorization initialization
This patch fixes UART system call authorization initialization (when
protection domain support is enabled) to only initialize the system call
entrypoint and authorization data structures once, prior to per-port
setup. Previously, if two UARTs were configured, the setup procedure for
the second UART would erase the system call authorization for the
first (console) UART, resulting in a crash upon the next attempt to
perform console output.

This patch adds a driver that wraps the generic 16X50 UART driver with
specific support for the two Intel Quark X1000 built-in UARTs.
