Subject: [PATCH] planck/rev7: Fix build without AUDIO_ENABLE

The watchdog code in `matrix.c` needs `#include <math.h>`; it broke with
`AUDIO_ENABLE = no`, because `quantum.h` no longer included `<math.h>`
implicitly.  Adding `#include <math.h>` fixes build of some user keymaps
which have `AUDIO_ENABLE = no`.
