Everest:Missing EXP_PRSNT GPIO pin for PCIe cards

In everest VPD JSON, "presence" section with expander presence gpio
pin information is missing for PCIe cards. Due to which during FRU
VPD collection, I2C line for PCIe card VPD is enabled without
checking if IBM specific PCIe card is actually present on the system.

This check is required for PCIe cards because the PCIe slot accepts
both IBM specific cards and any industry standard cards. So during VPD
collection before enabling the I2C line of PCIe card VPD, it's
recommended to check if IBM standard PCIe card is present on
IBM system.

Test:
'''
busctl call com.ibm.VPD.Manager /com/ibm/VPD/Manager com.ibm.VPD.Manager
CollectFRUVPD o "/xyz/openbmc_project/inventory/system/chassis/motherboard
/pcieslot2/pcie_card2"
