msm: camera: Enable pixel line buffer for ispif.

Enable pixel line buffer for ispif to handle fast incoming
data. This provides cusion to dowmstream components such as vfe
and helps in preventing UB buffer overflows.

720p video on 1080p panel have upscaling, mdp clk should not be
increased for this case. Also slightly increase mdp ib to make
sure there is no bw access bottleneck.

slub: use __SetPageSlab function to set PG_slab flag

To set page-flag, using SetPageXXXX() and __SetPageXXXX() is more
understandable and maintainable. So change it.

slub: Get rid of the node field

The node field is always page_to_nid(c->page). So its rather easy to
replace. Note that there maybe slightly more overhead in various hot paths
due to the need to shift the bits from page->flags. However, that is mostly
compensated for by a smaller footprint of the kmem_cache_cpu structure (this
patch reduces that to 3 words per cache) which allows better caching.

slub: Separate out kmem_cache_cpu processing from deactivate_slab
