commit 772dd0342727 ("mm: enumerate all gfp flags") define gfp flags with the help of BIT, while gfp_types.h doesn't include header file for the definition. This through an error on building memblock tests.
Let's include linux/bits.h to fix it.

Sasha, are you backporting 772dd0342727 ("mm: enumerate all gfp flags") to 6.6 and 6.8 kernels? Just checking because I didn't see any emails about that and can't find it in stable branches. If not, then this fixup is not needed there.
