Merge "Renesas ARM Based SoC Fixes for v3.19" from Simon Horman:

Renesas ARM Based SoC Fixes for v3.19

This pull request is based on the last round of SoC updates for v3.19,
Fourth Round of Renesas ARM Based SoC Updates for v3.19, tagged as
renesas-soc3-for-v3.19, merged into your next/soc branch and included in
v3.19-rc1.

- ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds

  Set .control_parent for all irqpin instances for sh73a0 SoC when booting
  using legacy C.

- ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds

  This fixes a long standing problem which has been present since
  the sh73a0 SoC started using the INTC External IRQ pin driver.

  The patch that introduced the problem is 341eb5465f67437a ("ARM:
  shmobile: INTC External IRQ pin driver on sh73a0") which was included
  in v3.10.
