For Raspberry Pi, we had the input clock rate to the pl011 fixed in the rpi.c file, but it may be changed by firmware due to user changes to config.txt. Since the firmware always sets up the uart (default 115200 output unless the user changes it), we can just skip our own uart init to simplify the boot process and more reliably get serial output.
