add sysfs for vibration intensity control

Allows incredible ~3% increase in vibration intensity. :P
Going down to about a third of the original intensity

Based on codeworkx's commit somewhere.

backport lowmemorykiller from CAF msm-3.4

this improves low memory behaviour greatly due to accounting for
lowmem_reserve as well as shmem pages.
