"vpll" is a misnomer. A clock input to a device should be named after
the usage in the device, not after the clock that drives it. On the
rk3568 the same clock is driven by the HPLL.
This patch adds "ref" as a new alternative clock name for "vpll"

Notes:
    Changes since v4:
    - Add Robs Ack
    
    Changes since v3:
    - Keep old clock name for compatibility reasons
