The pinctrls for the hym8563 interrupt line and fan-tach input
were both mistakenly defined as `pcfg_pull_none`. As these are
active-low signals (level-triggered, in the hym8563 case) which
may not be driven at times, these should really be pull-up. The
lack of any bias results in spurious interrupts.
Fix this by modifying the `rockchip,pins` properties as necessary
to enable the pull-up resistors.
