[PATCH 1/5] pci: rcar: Use dev_read_addr_index()

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Use dev_read_addr_index() which supports both live device tree and flat DT
backends, avoiding direct dependency on devfdt_* helpers.

While at here, correct the return value check.

No functional changes.
