This addresses an underlying problem since /dev/hw_random is used. The
issue is that EntropyMixer, which runs in system_server, needs to read
from /dev/hw_random, but thanks to our qualcomm ueventd, EntropyMixer
can never accress this node, resulting in warnings like this:
W EntropyMixer: Failed to add HW RNG output to entropy pool
W EntropyMixer: java.io.FileNotFoundException: /dev/hw_random (Permission denied)
AOSP ueventd handles this well, so just remove this line to get things
back to stage. This issue was never exposed because Google derps the
logging here, which is already fixed on Pie.

Specifying avb=<vbmeta-partition> is only necessary for first entry of
partition groups that use same vbmeta partition. The following entry can have
<vbmeta-parititon> part omitted.

Disabling UFS clkgate and ah8 during boot time helps in reducing
IO delays, which helps in reducing the total boot time. This change
will disable UFS clkgate and ah8 during early-init and then enable
it back after boot completion.

Two fstabs are needed to support different data unit number (dun)
size for ufs and emmc hardwares. This needs different encryption
flag in fstab to address the difference in dun size.
[ArianK16a: don't add the emmc fstab since all our devices are ufs]
Test: Verified bootup, vts_kernel_encryption, fscryptctl.

QMCS partition is not a read only partition, and risks the danger
of causing unnecessary disk churn when QMCS files are read.
Update QMCS partition to be mounted with the noatime option.

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.
