a2810d3cf8 Kernel: Use Processor::wait_check in loops waiting for HW to respond 
This gives the processor the hint that it is in a hot loop and allows us
to do other work in between

c460b84ebe Kernel: Add character device driver for the RPi "mini UART" (UART1) 
While the PL011-based UART0 is currently reserved for the kernel
console, UART1 is free to be exposed to the userspace as `/dev/ttyS0`.
This will be used as the stdout of `run-tests-and-shutdown.sh` when
testing the AArch64 kernel.
