[PATCH 1/3] lib: utils/timer: mtimer: add separate T-Head C9xx CLINT mtimer compatible

[Inochi Amaoto]

T-HEAD allows soc vendor to map the mtimer and mswi of C9xx clint on
different address, which may cause a misuse if use the same compatible
string, add a new timer compatible string to avoid this.
