[PATCH 0/3] T-Head C9xx CLINT support

[Icenowy Zheng]

This patchset tries to add support for T-Head C9xx's CLINT to OpenSBI.

For MSWI part, the T-Head CLINT is fully compatible with the SiFive one,
so it's just simply adding a compatible string.

For MTIMER part, it's first needed to implement a quirk for
MTIME-less timer (thus only MTIMECMP is present), then the compatible
string is added and bound to the quirk.

To instantiate such a T-Head flavored CLINT via DT, this patchset
depends on DT bindings declared in [1].
