The R8A7790's dtsi file i2c0, i2c1, i2c2, and i2c3 nodes have clock
references to the mstp3_clks clock node, however these clocks are in the
mstp9_clks node.

The error was introducted in 72197ca7 ("ARM: shmobile: r8a7790:
 Reference clocks") which is in Simon's current development tree.

This patch fixes the following error:

of_clk_src_onecell_get: invalid clock index 31
i2c-rcar e6508000.i2c: cannot get clock
i2c-rcar: probe of e6508000.i2c failed with error -2

When CONFIG_COMMON_CLOCK is enabled, call rcar_gen2_clocks_init() in the
timer init function to initialize the common clock framework before
initializing the clock sources. This will take care of clock
initialization when the r8a779[01] boards will be switched to
multiplatform kernels.

The PCI sub-system is not enabled by default on ARM and on certain
Renesas devices the build does not select it. This means that there
are configurations that do not allow the AHB-PCI bridge used for the
USB sub-systems to be built.

For the R8A7790, R8A7791 and EMEV-2 select MIGHT_HAVE_PCI to allow the
PCI drivers to be built. Also select MIGHT_HAVE_PCI for the multi-config
where there may be many Reneasas devices selected.

The break timer accesses hardware registers and thus requires the port
to be enabled. It currently ensures this by enabling the port at the
beginning of the timer handler, and disabling it at the end. However,
the enable/disable operations call the runtime PM sync functions, which
are not allowed in atomic context. The current situation is thus broken.

This change relies on non-atomic code to enable/disable the port. The
break timer will only be started from the IRQ handler, which already
runs with the port enabled. We just need to ensure that the port won't
be disabled with the timer running, and that's easily done by just
cancelling the timer in the port disable function.

MSTP clocks are gate clocks controlled through a register that handles
up to 32 clocks. The register is often sparsely populated.

Those clocks are found on Renesas ARM SoCs.
