Subject: [PATCH v24 1/4] dt-bindings: reset: npcm: add clock properties

Adding 25MHz reference clock and clock-cell properties to NPCM reset
document due to the registration of the npcm8xx clock auxiliary bus device
in the NPCM reset driver

The NPCM8xx clock auxiliary bus device has been registered in the NPCM
reset driver because the reset and the clock share the same register
region.
