The code for h2 and osk implicitly assumes that the tps65010
driver is built-in, in order to perform the initial regulator
setup.

This is fine for most real uses, but it does get into the way
of build testing with 'make randconfig', since we don't want
platforms to implicitly select device drivers and subsystems
such as I2C.

This patch by contrast changes the board files to not call
into the tps65010 driver when that is not built-in, allowing
us to build all configurations including some that will not
work properly on this hardware.

MSM7X00A has an open-coded version of debug_ll_io_init so it
can use MT_DEVICE_NONSHARED as required by the platform.

However, this fails to build on no-MMU kernels because the
debug_ll_addr function is not available. Since the iotable_init
function doesn't actually do anyting in this configuration,
we can simply get away by enclosing the broken function call
in an #ifdef, which seems to be the least ugly workaround.

When using CONFIG_IXP4XX_INDIRECT_PCI, we run into a recursive

in a build failure:

The DAVINCI_DA850_EVM board uses an unusual method to
enable the GPIO_PCA953X and KEYBOARD_GPIO_POLLED symbols,
which leads to the dependencies on these symbols being
ignored. As GPIO_PCA953X actually requires I2C, that
can lead to build failures when I2C is disabled.

This patch removes the duplicate symbol definitions
and instead enables them from the davinci_all_defconfig
file.

A different question whether we actually want to automatically
enable them at all or rather put them into defconfig,
but that should be a separate patch.

Since commit 9e8147bb
"ARM: imx6q: move low-power code out of clock driver"
the kernel fails to boot on i.MX6Q/D if preemption is
enabled (CONFIG_PREEMPT=y). The kernel just hangs
before the console comes up.

The above commit moved the initalization of the low-power
mode setting (enabling clocked WAIT states), which was
introduced in commit 83ae2098
"ARM: imx: correct low-power mode setting", from
imx6q_clks_init to imx6q_pm_init. Now it is called
much later, after all cores are enabled.

This patch moves the low-power mode initialization back
to imx6q_clks_init again (and to imx6sl_clks_init).

Due to commit 88f718e3
"ARM: pxa: delete the custom GPIO header" some drivers fail
compilation, for example like this:

In file included from sound/soc/pxa/spitz.c:28:0:
sound/soc/pxa/spitz.c: In function ‘spitz_ext_control’:

 #define SPITZ_SCP_GPIO_BASE (PXA_NR_BUILTIN_GPIO)
(etc.)

This is caused by implicit inclusion of <mach/irqs.h> from
various board-specific headers under <mach/*> in the PXA
platform. So we take a sweep over these, and for every such
header that uses PXA_NR_BUILTIN_GPIO or PXA_GPIO_TO_IRQ()
we explicitly #include "irqs.h" so that we satisfy the
dependency in the board include file alone.
