Refactoring
- Don't wildcard-import from arch modules. Make it explicit.
- Put translation table code into its own module.
- Put boot code in boot.rs instead of cpu.rs
- Other minor changes, most memory subsystem.

Bump compiler version.
We have to remove the `#[naked]` attribute from `_start` for now, since it emits
a warning now when used with non-asm statements in the function body. For now,
just hope for the compiler's mercy to not emit code using the stack pointer
before we've actually set up a stack.

Update dependencies
register-rs 1.0.0 now uses UnsafeCell internally, which means we lost the Copy
derive on InMemoryRegister.

Therefore, a small set of changes was needed in the MMU driver to dance around
the static array init depending on a Copy type.

GPIO: Fix RPi4 driver init
The RPi4 GPIO pull-up/pull down sequence is done differently than on the
RPi3. Switch to using the correct way.

Also, configure pull-ups for both UART pins.

Switch to GCC objdump and nm
The GCC versions of `objdump` and `nm` seem to have better out-of-the-box
support (for AArch64). Demangling works better, and instructions in objdump are
presented as 4 bytes instead of 4 * 1 bytes, which helps a lot.

Hence, switch to the GCC versions for now until LLVM has caught up.
