phy: qcom-qmp-combo: fix out-of-bounds clock access

commit 001281c551a57859accae06a801712d4f81f466d upstream.

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.
