arm64: dts: qcom: msm8996: don't use underscore in node name

[ Upstream commit 84f3efbe5b4654077608bc2fc027177fe4592321 ]

We have underscore (_) in node name leading to warning:

arch/arm64/boot/dts/qcom/apq8096-db820c.dt.yaml: clocks: $nodename:0: 'clocks' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
arch/arm64/boot/dts/qcom/apq8096-db820c.dt.yaml: clocks: xo_board: {'type': 'object'} is not allowed for {'compatible': ['fixed-clock'], '#clock-cells': [[0]], 'clock-frequency': [[19200000]], 'clock-output-names': ['xo_board'], 'phandle': [[115]]}

Fix this by changing node name to use dash (-)
