Maggie White ce0ecde565 UFS-specific runtime I/O tuning
Tested 1/2x, 1x, 2x, and 4x the current readahead buffer and noop and
cfq I/O schedulers for /dev/block/sda, which contains /data. The most
consistent performance boost was seen across all UFS vendors and storage
sizes using cfq and a readahead buffer of 1024.
Note: testing was done on Walleye, not Taimen

Bug: 38000161
Test: Compared 1P app launch times using app-launcher for schedulers
(noop, cfq) and readahead buffer sizes (128,512,1024,2048)
