a731c7e369 platform: Replace CLINT library usage with ACLINT library
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.

ec5274b04c platform: implement K210 system reset
Implement rebooting the K210 via the system reset extension.

72a0628c7e platform: Use one unified per-HART stack size macro for all platforms
As of today all platforms use 8KB of per-HART stack hence there is
no need for each platform to define its own macro or use the magic
number. Create one macro for all platforms. Platform still can use
its own version if needed.

9dfe720579 kendryte/k210: remove sysctl code
Directly implement frequency discovery, making the sysctl code
unnecessary. While at it, Move all macro definitions from platform.c
into platform.h and cleanup that file, removing the need for the
Apache 2.0 license and Canaan Inc copyright.

There are several places in the source tree that have:

  32bit, 32 bit, 64bit, 64 bit

Fix by using the conventional names with a hyphen.

fbf986ac2a all: Annotate some tables to have clang-format leave them alone
One of the shortcomings of clang-format is that it doesn't allow
for aligned define tables, which is used for a number of constants.

Add annotation to disable the automatic formatting where needed.

28d1dd2430 platform: Use CSR_<FOO> instead of <foo> for csr_*()
Some older toolchains may not have all the csr's defined. Update all
the csr functions to use the CSR_ #define values instead of the
toolchain defined values.
