arch/x86: Fix compilation error
arch_dcache_range() function does not exist anymore, nor K_CACHE_WB
macro. Removing it entirely.
arch_dcache_flush_range() signature changed, so relevantly applying
these.
#include <stdbool.h>
/**
- * @brief Flush cache lines to main memory
- *
* No alignment is required for either <virt> or <size>, but since
* sys_cache_flush() iterates on the cache lines, a cache line alignment for
* both is optimal.
*
* The cache line size is specified via the d-cache-line-size DTS property.
