clk: qcom: ipq5210: add 24MHz rate for USB UTMI clock

The USB UTMI reference clock must operate at 24 MHz, as recommended
by the hardware team, for reliable USB operation.

Validation showed that USB 3.2 hub enumeration with USB 2.0 devices
fails when the UTMI reference clock is not configured to the required
24 MHz rate. Configuring the UTMI reference clock to 24 MHz to resolve
the enumeration failure and ensure successful device detection.
