We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>

expression ret;
struct platform_device *E;

ret =

platform_get_irq(E, ...)

platform_get_irq_byname(E, ...)

While we're here, remove braces on if statements that only have one

In case of driver probe and pm resume we need to check that the cryptocell
hardware reset cycle is completed. during the reset cycle that Cryptocell
provide read only access to the APB interface which allows to verify
through the CC registers that the reset is completed. Until reset
completion we assume that any write/crypto operation is blocked.

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 8234f6734c
("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.
