This patch removed the old writeout policy tune which was never touched since
2009. In the meantime, most of Android devices are equipped with over 4GB DRAM
and very fast flash storages like UFS, which becomes more like desktop or
servers in 2009. So, it'd be worth to go back to use the default kernel configs.

Scheduler will use pure CFS before boot complete, and change to
EAS after boot complete, so set capacity margin here.
Bug: 153216544
Test: capacity margin set as expected

-Switch to LZ4 for better overall performance
-Set max_comp_streams to num of cores since upstream also moves this to
percpu.
-Set page-cluster to 0 as the incremental cost of reading 1 page at a
time is negligible for zram
Bug: 38249616
Test: boot and run zram-perf showing better performance

Allows us to check the idle state of the display in order to use perf
