drm/meson: use unsigned long long / Hz for frequency types


This patch triggers:

Building arm:allmodconfig ... failed
--------------
Error log:
drivers/gpu/drm/meson/meson_vclk.c:399:17: error: this decimal constant is unsigned only in ISO C90 [-Werror]
399 | .pll_freq = 2970000000,

and other similar problems. This is with gcc 13.4.0.
Sorry to hear that this is causing issues.
Are you only seeing this with the backport on top of 5.15 or also on
top of mainline or -next?

If it's only for 5.15 then personally I'd be happy with just skipping
this patch (and the ones that depend on it).

It's already merged, and I see these errors in the Android build reports
now. I think they've just disabled the driver entirely to get around it :(
Can you confirm that only 5.15 is affected - or do you also see
problems with other stable versions?


Only 5.15.y is affected. I think that is due to "-std=gnu11" which was introduced
around v5.18.
