swiotlb: using SIZE_MAX needs limits.h included
[ Upstream commit f51778db088b2407ec177f2f4da0f6290602aa3f ]
After merging the drm-misc tree, linux-next build (arm
multi_v7_defconfig) failed like this:
In file included from drivers/gpu/drm/nouveau/nouveau_ttm.c:26:
include/linux/swiotlb.h: In function 'swiotlb_max_mapping_size':
include/linux/swiotlb.h:99:9: error: 'SIZE_MAX' undeclared (first use in this function)
99 | return SIZE_MAX;

include/linux/swiotlb.h:7:1: note: 'SIZE_MAX' is defined in header '<stdint.h>'; did you forget to '#include <stdint.h>'?

Caused by commit
abe420bfae52 ("swiotlb: Introduce swiotlb_max_mapping_size()")
but only exposed by commit "drm/nouveu: fix swiotlb include"
Fix it by including linux/limits.h as appropriate.
