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.
