[LTP] [PATCH] Fix memcontrol02 test failure on powerpc.

[LTP] [PATCH] Fix memcontrol02 test failure on powerpc.

[Pavithra]

memcontrol02 test is failing on PowerPC with 50MB allocation. Increase to
100MB for both anonymous and page cache tests, and bump minimum
device size from 300MB to 400MB accordingly.

The patch is fixing a test regression so it needs a Fixes: tag pointing
to the commit that introduced the 50 MB allocation values. Please add it
at the end of the commit message body, before the Signed-off-by line.
