[ Upstream commit d8a5b59c5fc75c99ba17e3eb1a8f580d8d172b28 ]
The SM8250 only uses three clocks but the DP configuration erroneously described four clocks.
In case the DP part of the PHY is initialised before the USB part, this would lead to uninitialised memory beyond the bulk-clocks array to be treated as a clock pointer as the clocks are requested based on the USB configuration.
