Subject: [PATCH] zephyr: spinlock: Fix compile time warnings

With Zephyr, spinlock.h needs to know `struct k_spinlock`
definition.

Include, Zephyr's <kernel.h> header.

This fixes compile time warnings like this:

z/modules/audio/sof/zephyr/../src/include/sof/schedule/ll_schedule_domain.h:
In function 'domain_init'"
z/modules/audio/sof/zephyr/../src/include/sof/schedule/ll_schedule_domain.h:93:18:
warning: passing argument 1 of 'k_spinlock_init' from incompatible
pointer type [-Wincompatible-pointer-types]
