P11 JSON:Refactored rainier 1S4U system JSON (#465)

This commit has rainier 1S4U system JSON refactored with the following
changes:

1. Add devTree tag.
2. Add backupRestoreConfigPath tag.
3. Add serviceName in every parent FRU and sub FRU section.
4. Updated inventoryPath tag with complete path.
5. Removed unused tag "gpioI2CAddress"
6. Removed busType, driverType as we have systemCmd tag
   which has command to bind.
7. Added Slot interface to all NVMe drives
8. Modified preAction and PostFailAction sections as per P11 code
   and added postAction if required for following FRUs:
	1. Control panel display
	2. PCIe4 x16 or PCIe5 x8 adapter
	3. OpenCAPI adapter
	4. PCIe5 x8 adapter (pcie_card7)
	5. PCIe5 x8 adapter (pcie_card9)
	6. PCIe5 x8 adapter (pcie_card11)
	7. PCIe4 x8 adapter
9. Added systemCmd bind preAction section for dimms 0-7

TODO:

10. GPIO presence preAction for DIMMs has not been added as
    "presence-cpx" GPIO lines are not defined in Rainier .dts file.

Test:

This JSON file has not been tested yet due to unavailability of Rainier
1S4U system.
