Inochi Amaoto 942e02e150 dt-bindings: interrupt-controller: Add Sophgo sg2042 CLINT mswi
The clint of Sophgo's sg2042 is based off IP designed by T-HEAD, and
implements the not yet frozen ACLINT spec. This spec seems to be
abandoned, and will not be frozen in the predictable future.
Frozen specs required by the RISC-V maintainers before merging content
relating to those extensions, therefore a generic compatible is not
appropriate.
Instead, add new vendor specific compatible strings to identify mswi of
sg2042 clint.
