patch: Restructure timer patches
Redesign timer patch file structure for better modularity. Now,
`timer/<chip>.yaml` defines all timer peripherals for a chip and uses
peripheral-level includes for patching the actual peripheral. The
actual peripheral patches live in `timer/dev/<type>.yaml`.
The intermediate `<chip>.yaml` file is needed because peripheral-level
includes are not allowed in top-level files.

macros: Add a #[entry] macro
Add a #[entry] macro for declaring the entry-point of the program,
similar to what cortex-m-rt is doing.

Add patches for ADC peripherals
Add a patch to fixup a few registers in the ADC peripheral
for ATmega328P, ATmega32U4, ATmega1280, and ATmega64.
ci: Fix nightly to 2020-07-12
Fix nightly to a version where rustfmt was still available.

make: Allow overriding rustup toolchain
Allow overriding the rustup toolchain used for rustfmt by invoking make
like this:
make RUSTUP_TOOLCHAIN=nightly-2020-07-12
This will (hopefully) help when working with nightly versions where
rustfmt is unavailable.

Use llvm_asm!() instead of asm!()
The asm!() feature was changed to a new syntax which this project did not yet
adopt. The old asm!() is now available as llvm_asm!(). Switch to that to
support nightly build.
See PR #27 for details.
