Add compatible string and property for the SiFive CLINT v2.
Signed-off-by: Nick Hu <nick.hu@sifive.com>
Reviewed-by: Samuel Holland <samuel.holland@sifive.com>

- v2 changes:
- Don't allow sifive,clint2 by itself. Add '-{}' to the first entry
- Mark the sifive,fine-ctr-bits as the required property when
the compatible includes the sifive,clint2
