arm64: dts: qcom: sc8280xp: Vote for CX in USB controllers

[ Upstream commit 49d22b1f207325e5699f24c5e22dbc242e977419 ]

Running GCC_USB30_*_MASTER_CLK at 200MHz requires CX at nominal level,
not doing so results in occasional lockups. This was previously hidden
by the fact that the display stack incorrectly voted for CX (instead of
MMCX).
