peppy: Disable unused clocks
CLKOUT for PCIE ports 2-5 and CLKOUT_XDP are not used and can be disabled.
This change was modled after the change made in Falco: Falco-Change-Id: I0f996e90f0ae42780de3a0c8dc5db00ec600748b
The only difference per schematic for Peppy was PCIe 1 supports a NGFF interface. PCIe 0 is connected to WLAN.
