Kernel/aarch64: Add pre_init function for that sets up the CPU and MMU

Browse source 
This is a separate file that behaves similar to the Prekernel for
x86_64, and makes sure the CPU is dropped to EL1, the MMU is enabled,
and makes sure the CPU is running in high virtual memory. This code then
jumps to the usual init function of the kernel.
