powerpc/virtex: Fix booting of Xilinx FPGAs with 16550 for 405 and 440
The following changes add processing to initialize the Xilinx 16550 UART
in the boot wrapper for Virtex targets without firmware. Normally the
boot wrapper assumes that the serial port has already been initialized by
firmware.
The wrapper was also modified to add the 440 build.
