Call spin_lock_init() before the spinlocks are used, both in early init
and probe functions preventing a lockdep splat.
I have been observing lockdep complaining [1] during boot on my a80 optimus [2]
when CONFIG_PROVE_LOCKING has been enabled. This patch resolves the splat,
and has been tested on a few other sunxi platforms without issue.

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.

ARM: dts: disable CCI on exynos5420 based arndale-octa
The arndale-octa board was giving "imprecise external aborts" during
boot-up with MCPM enabled. CCI enablement of the boot cluster was found
to be the cause of these aborts (possibly because the secure f/w was not
allowing it). Hence, disable CCI for the arndale-octa board.

drivers: bus: check cci device tree node status
The arm-cci driver completes the probe sequence even if the cci node is
marked as disabled. Add a check in the driver to honour the cci status
in the device tree.

ARM: rockchip: disable jtag/sdmmc autoswitching on rk3288
rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.
It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.
Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.
