ccree irq may be shared with other devices, in order to prevent ccree isr
handling while device maybe suspended we added a check to verify that the
device is not suspended.

crypto: ccree - add missing inline qualifier2019-02-22T04:40:56ZGilad Ben-Yossef2019-02-11T14:27:58Zurn:sha1:f1071c3e2473ae19a7f5d892a187c4cab1a61f2e
Commit 1358c13a48c4 ("crypto: ccree - fix resume race condition on init")
was missing a "inline" qualifier for stub function used when CONFIG_PM
is not set causing a build warning.

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.
