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.
