Instead of relying on CONFIG_MEMORY_START for memory
base address, let each romImage board header file
specify this information.
This is reworks code not to rely on CONFIG_MEMORY_START
which in turn is needed for ARCH_MULTIPLATFORM.

Remove the ATAGS data structure from head-shmobile.S
since a default ATAGS is already provided by the code
in arch/arm/kernel/atags_parser.c. Passing a NULL as
ATAGS is valid. For actual hardware specific setup
the fixup callback in the board code may be used.

This is V2 of the mach-shmobile uImage load address rework patch.
Rework the mach-shmobile uImage load address calculation by storing
the per-board load addresses in Makefile.boot. This removes the
CONFIG_MEMORY_START dependency from Makefile.boot, and it also makes
it possible to create safe kernel images that boot on multiple boards.
This is one of several series of code that reworks code not to rely on
CONFIG_MEMORY_START/SIZE which in turn is needed for ARCH_MULTIPLATFORM.

"gpio-rcar: Support IRQ_TYPE_EDGE_BOTH" adds support to the R-Car GPIO
driver for IRQ_TYPE_EDGE_BOTH. As hardware support for this feature is
not universal for all SoCs a flag, has_both_edge_trigger, has been
added to the platform data of the driver to allow this feature to be
enabled.
As the r8a7790 SoC hardware supports this feature enable it.

The list of functions selected by the MOD_SEL2 register was missing
an entry. This caused all entries after this to modify the MOD_SEL2
register incorrectly.
This bug showed up when selecting i2c2_c pins on the Renesas Hurricane board.
This bug has been present since pinmux support was added for the
r8a7779 SoC by 881023d28b ("sh-pfc: Add
r8a7779 pinmux support") in v3.8-rc4.

The sh73a0 has an internal power gate on the VCCQ power supply for the
SDHI0 device that is controlled (for some strange reason) by a bit in a
PFC register. This feature should be exposed as a regulator.
As the same register is also used for pin control purposes there is no
way to achieve atomic read/write sequences with a separate regulator
driver. We thus need to implement the regulator here.
