[PATCH RESEND 0/2] drm: add drm_warn_ratelimited() and convert ivpu to use it

[Dawid Osuchowski]

This patch set adds drm_warn_ratelimited() to the DRM print helpers
and updates the ivpu driver to use the warning-level variant instead
of err-level logging. The new helper matches the existing rate-limited
logging pattern and gives drivers a consistent way to emit warning
messages without spamming the kernel log.

This change improves logging correctness and consistency for drivers
that need rate-limited warnings.

[PATCH RESEND 1/2] drm/print: add drm_warn_ratelimited logging macro

[Dawid Osuchowski]

Add a drm_warn_ratelimited() macro to complement the existing
drm_err_ratelimited(), providing rate-limited logging at warning level
for drivers that need it.
