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.

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.
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.

Fix compatibility with svd2rust 1.16.1
svd2rust now generates a module containing generic descriptions which
the individual register definitions are based on. Fix the code
generation to deal with this module.

Implement interrupts
This commit adds a new feature-flag `rt` which, when enabled, adds the
`#[interrupt]` procedural macro to define an interrupt handler. Unlike
the implementation in cortex-m, this version needs an attribute which is
the name of the chip the interrupt is for. In code, an interrupt
handler might look like this:
#![feature(abi_avr_interrupt)]
#[avr_device::interrupt(atmega32u4)]
fn INT6() {
// Do Something
}
Closes #1.
