[edk2-platforms][PATCH V3 1/1] Silicon/ARM/NeoverseN1Soc: Update CCIX PNP ID

["sahil" <sahil@arm.com>]

The PNP ID 0x0A09 used for CCIX host bridge in the current code is
not defined in any specification and is therefore incorrect.

Also, there is no need for a separate ID for CCIX host bridge,
for the following reasons:

1. CCIX doesn't have any host specific requirements/ingredients as such.
2. CCIX protocol messages flow over regular PCIe.
3. CCIX devices and root ports are natively discovered using the CCIX DVSEC.

Therefore, reuse PCIe PNP ID for CCIX.
