Revert to assembly boot code
It is too risky to rely on the compiler to not insert any operations using the
stack.

Having a stack-setting call in Rust using the cortex-a crate as the first action
in a Rust-only _start() function does not work if you're subsequently using the
stack, because the compiler often inserts the operations to make room on the
stack to prepare a function call BEFORE the call to set the stack, which crashes
the boot process.

Hence, keep on using a small piece of assembly boot code throughout.

- 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.

01: Remove LTO to fix linking bug.
For some reason, LTO caused "_start" to start at 0x00080020
instead of 0x00080000.

Big restructuring for more modularity
- Make architecture code separate from BSP code
- Make BSPs pull in drivers from a generic folder
    - Enables reuse of drivers between different BSPs.
