Refactor ATCSMU (System Management Unit) support by moving it from a
system utility into a dedicated FDT-based HSM driver.
Key changes include:
- Moving the functions in lib/utils/sys/atcsmu.c into the new HSM driver
- Moving hart start and stop operations on AE350 platform into the new
HSM driver
- Converting the assembly-based functions in sleep.S to C code for the
readability
- Updating the ATCWDT200 driver

We update system drivers makefile to use kconfig for enabling/disabling
drivers. To avoid compile errors, we also enable appropriate system
drivers for each platform.

The ACLINT devices are backward compatible with SiFive CLINT
so we replace all CLINT library usage in various platforms
with ACLINT library. As a result of this replacement, the
CLINT library is not used by any part of OpenSBI hence we
remove it.

This patch factor-out SiFive test device related stuff into
it's own source file from qemu/virt platform. In future, we
can find SiFive test device address from device tree as well.

The drivers and libfdt are built as libsbiutils.a
instead of libplatsbi.a.
libsbiutils.a are not built per platform specific. Thus,
enable all drivers by default.

Currently, platform/common contains platform/non-platform specific
common minimal drivers and libraries. This is helpful is all platforms
are built within opensbi framework.
Move them to lib/utils so that any external platform code also can
reuse the minimalistic drivers or other common libraries.
This patch doesn't introduce any functional changes.
