atmega328p, pb: Split EIMSK INT field into 2
The INT0 and INT1 fields in the EIMSK register were incorrectly
combined into a 2 bit field, split into individual bits.
Also allow write access to PRR0 and PRR1 in ATmega328PB.
atmega328p: Make PRR register writable
patches: Include _svd tag
The _svd: tag is needed for upstream svdtools to find the corresponding
svd file for each patch.

Make the PINx registers writeable
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.

Add patches for ADC peripherals
Add a patch to fixup a few registers in the ADC peripheral
for ATmega328P, ATmega32U4, ATmega1280, and ATmega64.
atmega328p: Add missing patches
This commit adds patches for ATmega328P by copying the commons from ATmega32U4, omitting PLL because the 328p lacks that feature (#11)
