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.
