modules/cmsis-dsp: Don't use Zephyr stdint.h

keith-packard · keith-packard · commit 0d7c0d86246c · 2025-07-10T10:49:17.000-07:00
Zephyr replaces the toolchain version of stdint.h to define uint32_t and
int32_t as int rather than long. This breaks the ARM MVE intrinics which
require uint32_t to be defined as unsigned long.

Define 'ZEPHYR_USE_TOOLCHAIN_STDINT_H_' as that causes zephyr_stdint.h to
be skipped, ensuring that the normal stdint.h types are used instead.
