Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>

This patch converts the drivers in drivers/crypto/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

The Security function on the AMCC SoCs has multiple engines within a
single MMIO range.  The crypto driver currently enables the 3DES
functionality by doing a blind write to the device control register.
This can unintentionally disable other functions like the PKA or TRNG
when the driver is loaded.

Perform a read/modify/write to enable the 3DES function instead.

Get rid of old users of of_platform_driver in arch/powerpc.  Most
of_platform_driver users can be converted to use the platform_bus
directly.

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.
