platform: Replace CLINT library usage with ACLINT library

Browse source 
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.
