UPSTREAM: soc/intel/skylake: Enable bus master for sata
The bus master needs to be enabled so that
the busy bit in AHCI PORT_TFDATA will be cleared
by controller when depthcharge tries to wait
for sata to complete spin-up during AHCI init.
Otherwise, the timeout will happen and cause
5 seconds delay in depthcharge.
BUG=b:37639063
BRANCH=none
TEST=verify that the sata timeout is gone in
depthcharge
