Subject: [PATCH v27 1/3] dt-bindings: reset: npcm: add clock properties

This commit adds a 25MHz reference clock and clock-cell properties to
the NPCM reset document. The addition is necessitated by the integration
of the NPCM8xx clock auxiliary bus device into the NPCM reset driver.

The inclusion of the NPCM8xx clock properties in the reset document is
crucial as the reset block also serves as a clock provider for the
NPCM8xx clock. This enhancement is intended to facilitate the use of the
NPCM8xx clock driver.
