[PATCH] dt-bindings: fix compilation error of the example in intel,lgm-emmc-phy.yaml

[Dafna Hirschfeld <dafna.hirschfeld@collabora.com>]

Running:
export DT_SCHEMA_FILES=Documentation/devicetree/bindings/phy/intel,lgm-emmc-phy.yaml
'make dt_binding_check'

gives a compilation error. This is because in the example there
is the label 'emmc-phy' but labels are not allowed to have '-' sing.
Replace the '-' with '_' to fix the error.
