hw/arm: Connect PWM fans in NPCM7XX boards
This patch adds fan_splitters (split IRQs) in NPCM7XX boards. Each fan
splitter corresponds to 1 PWM output and can connect to multiple fan
inputs (MFT devices).
In NPCM7XX boards(NPCM750 EVB and Quanta GSJ boards), we initializes
these splitters and connect them to their corresponding modules
according their specific device trees.
