Change PcieType to PCIeType

In the patch:
https://github.com/openbmc/bmcweb/commit/62cd45af311e7741064c114581ba34186d6e508c

Mismatch of PCIeType from pcie.hpp to PCIeDevice_v1.xml.In function requestRoutesSystemPCIeDevice,
PCIeType mentioned for PCIeInterface details, was written as PcieType but in PCIeDevice_v1.xml,
property name is PCIeType which was giving error in the validator.

Tested using RedfishServiceValidator:
