[PATCH v5 2/3] platform/x86: amd-pmc: Store the pci_dev instance inside struct amd_pmc_dev

[Sanket Goswami <Sanket.Goswami@amd.com>]

Store the root port information in amd_pmc_probe() so that the
information can be used across multiple routines.

Signed-off-by: Sanket Goswami <Sanket.Goswami@amd.com>

Changes in v5:
- Remove pci_dev_put() from amd_pmc_remove() as its no longer required.

Changes in v4:
- No change.

Changes in v3:
- Add pci_dev_put() in amd_pmc_remove().

Changes in v2:
- Store the rdev info in amd_pmc_probe() as suggested by Hans.
