[PATCH 6/9] dt-bindings: timer: Add MIPS P8700 ACLINT MTIMER

[Aleksa Paunovic via B4 Relay <devnull+aleksa.paunovic.htecgroup.com@kernel.org>]

From: Aleksa Paunovic <aleksa.paunovic@htecgroup.com>

Document the MIPS P8700 ACLINT MTIMER.
Extend support for both mtimecmp and mtime registers
within the ACLINT MTIMER, identified via reg-names.
