When we think of Kconfig, we usually think of features that we like
to enable or not. Ideally, we wouldn't use Kconfig to fix a build
issue, although sometimes it might make sense. With Kconfig it's hard
to guarantee that the fix is universal. We can only say that it works
for the set of tested configurations. In the majority of cases, it's
preferable to let the linker figure things out for us.
The reverted commit attempted to fix a build issue by adding an
invisible Kconfig option. This is wrong in several ways:
It invents a new Kconfig variable when CONFIG_HASH already
exists for the same purpose.
Second, hash-checksum.c makes use of the hash_progressive_lookup_algo()
symbol, which is only provided with CONFIG_HASH, but this dependency
was not expressed in the reverted patch.
It feels like Kconfig is turning into a listing of all available
source files, and a buffet to 'select' which ones to compile. The
purpose of this revert is to enable the next change to make use of
CONFIG_HASH instead of adding to Kconfig.

The AM64x SoC uses a central Device Management and Security Controller
(DMSC) processor that manages all the low-level device controls
including the system-wide SoC reset. The system-wide reset is managed
through the system reset driver.
Add a sysreset controller node as a child of the dmsc node to enable
the "reset" command from U-Boot prompt for the K3 AM642 SK.
