fac99683a7 Switch kernel hz to 1000. 
While investigating performance problems around 'docker run' times, it
was observed that a large amount of time was spent in network namespace
creation.  Of that time, a large portion involved waiting for RCU grace
periods to elapse.  Increasing HZ causes the periodic timer to check for
quiesced periods more frequently, which consequently reduces the amount
of time RCU callers spend waiting for grace periods and in barrier
waits.

By itself, this change took the amount of time to execute a 'docker run
hello-world' down to 570ms from over 2000ms on 4.14, and down to 390ms
from 1260 on 4.17 and 4.18.

7a4233dec5 kernel: Add USB storage support for x86_64 and arm64 
This is useful for some baremetal configs, such as using
USB sticks on a RPi3. I enabled it for x86_64 as well
to keep the differences smaller.

551e00630c kernel: Enable SERIAL_DEV_BUS on arm64 
Note, the depeding SERIAL_DEV_CTRL_TTYPORT defaults to
'N' with the 4.14.x kernel and 'Y' for the 4.16.x kernel.
I chose to stick with the defaults.

This may fix the serial console issue, I've seen on the RPi3
with 4.14.x kernels.
