commit 3499efbeed39d114873267683b9e776bcb34b058 upstream.
During power management suspend the driver need to prepare the device
for the power down operation and as a last indication write to the
HOST_POWER_DOWN_EN register which signals to the hardware that
The ccree is ready for power down.

crypto: ccree - fix resume race condition on init2019-02-08T07:28:02ZGilad Ben-Yossef2019-02-07T13:36:11Zurn:sha1:1358c13a48c43f5e4de0c1835291837a27b9720c
We were enabling autosuspend, which is using data set by the
hash module, prior to the hash module being inited, casuing
a crash on resume as part of the startup sequence if the race
was lost.
This was never a real problem because the PM infra was using low
res timers so we were always winning the race, until commit 8234f6734c5d
("PM-runtime: Switch autosuspend over to using hrtimers") changed that :-)
Fix this by seperating the PM setup and enablement and doing the
latter only at the end of the init sequence.

Introduce basic low level Arm TrustZone CryptoCell HW support.
This first patch doesn't actually register any Crypto API
transformations, these will follow up in the next patch.
This first revision supports the CC 712 REE component.
