arm64: dts: qcom: sm8250: Fix EPSS L3 interconnect cells

Qualcomm EPSS L3 Interconnect does not take path (third) argument.  This
was introduced by commit b5a12438325b ("arm64: dts: qcom: sm8250: Use 2
interconnect cells") which probably wanted to use 2 cells only for RPMh
interconnects.

  sm8250-hdk.dtb: interconnect@18590000: #interconnect-cells:0:0: 1 was expected

Fixes: b5a12438325b ("arm64: dts: qcom: sm8250: Use 2 interconnect cells")
