57a4955f13 [S390] zcrypt: fix Kconfig dependencies
warning: (ZCRYPT && CRYPTO && CRYPTO_HW && S390 && ZCRYPT=y) selects
ZCRYPT_MONOLITHIC which has unmet direct dependencies (ZCRYPT=m)

ZCRYPT_MONOLITHIC should not depend on ZCRYPT="m" when it gets

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.

1ab1d63a85 of/platform: remove all of_bus_type and of_platform_bus_type references
Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus.  This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.

Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim.  At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.

4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

60f208d783 crypto: talitos - add support for sha224
SEC h/w versions 2.1 and above support sha224 via explicit instruction.

Performing sha224 ahashes on earlier versions is still possible because
they support sha256 (sha224 is sha256 with different initial constants
and a different truncation length).  We do this by overriding hardware
context self-initialization, and perform it manually in s/w instead.

Thanks to Lee for his fixes for correct execution on actual sec2.0 h/w.
