[PATCH v3 06/18] PCI: rcar-gen4: Move deinitialization helpers before SoC initialization

[Koichiro Den <den@valinux.co.jp>]

Move common_deinit() next to common_init(), ahead of
rcar_gen5_pcie_init(), which will call it when PHY initialization fails.
Place rcar_gen5_pcie_deinit() before rcar_gen5_pcie_init() as well.

Keep these moves separate from the following initialization refactoring
to make that patch easier to review. The function bodies are unchanged.

No functional changes.

Changes in v3:
  - Add Marek's R-b tag.
  - Use function names in the commit message to avoid ambiguous Gen5
    references. No code changes.
