aarch64 Rust OS demo

An example of combining various libraries for aarch64 OS development in Rust.

This crate demonstrates how to use a number of aarch64-specific crates:

• aarch64-paging for page table management.
• aarch64-rt for the entry point and exception handling.
• arm-sysregs for accessing system registers.
• smccc for PSCI and other standard SMC calls to EL3 firmware.

As well as some more general crates for embedded development:

• buddy_system_allocator for heap allocation.
• dtoolkit for device tree parsing.
• percore for exception masking.

And some device driver crates:

• arm-gic for the Arm Generic Interrupt Controller.
• arm_pl031 for the PL031 real-time clock.
• arm-pl011-uart for the PL011 UART.
• uart_16550 for the 16550 UART.
• virtio-drivers for various VirtIO devices.
