arm64: dts: qcom: apq8096: fix fixed regulator name property

Correct the typo in 'regulator-name' property.

  apq8096-ifc6640.dtb: v1p05-regulator: 'regulator-name' is a required property
  apq8096-ifc6640.dtb: v1p05-regulator: Unevaluated properties are not allowed ('reglator-name' was unexpected)
