arm64: dts: qcom: ipq5332: Represent xo_board as fixed-factor clock

Browse Source 
The xo_board clock is derived from the 48 MHz WiFi output clock (divided
by 2), and not a standalone fixed frequency source.

The previous implementation incorrectly modelled it as a fixed-clock with
fixed frequency, which doesn't reflect the actual hardware clock tree.
Update for fixed-factor-clock compatibility, and properly reference the
source clock.
