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.
README: Use ATmega64 as an up-to-date example
Signed-off-by: Rahix <rahix@rahix.de>
Add basic support for ATmega64
Pull in the ATDF file from Microchip and add all the necessary plumbing
around the code-base to make it compile. Not tested against real
hardware and no device-specific patches are included yet.

interrupts: Fix sed expressions for parsing interrupt list
The format for the interrupt sources changed which silently made
gen-intr-lut.sh no longer generate any interrupt names. Fix the
expressions so interrupt names are recognized again and the macro
can be used for generating interrupt definitions again.

make: Use a patchfile instead of weird sed expr
As reported in issue #24 the sed(1) expression used to patch the generated
`mod.rs` does not work on MacOS (BSD sed). Instead, use patch(1) and a small
patchfile to accomplish the same task.
