This patch updates the register definitions for DA9063 to support the
production silicon variant code ID (0x5). These changes are not backwards
compatible with the previous register definitions and can only be used
with the production variant of DA9063.

Since we do not want to add new platform IDs for the syscon driver,
there is no reason to iterate over IDs. This patch simplifies
syscon_match_pdevname() function to remove such iteration.

Since this code has been marked broken for some time a few genirq
tree wide changes weren't made. set_irq_wake() was renamed to
irq_set_irq_wake() in commit a0cd9ca2 (genirq: Namespace
cleanup, 2011-02-10) and commit 10a8c383 (irq: introduce entry

The pm8xxx-irq.c code is practically mandatory given that the
pm8921-core driver will WARN about it missing and the Kconfig
marks it as default y when a PM8xxx chips is enabled. The only
reason the file was split out was because we planned to support
other pm8xxx chips with different pm8xxx-core.c files. Now that
we have DT on ARM this isn't necessary because we should be able
to support all the ssbi based PM8xxx chips in one driver and one
file with no data bloat. Let's move this code into the only
driver that uses it right now (pm8921) so that it's always compiled when
needed. In the future we can rename pm8921-core.c to something
more generic.

This patch allows GPIO driver to cache GPIO_LVL output registers. The aim is to
support chipsets on which GPIO_LVL value can't be read for output pins.

Caching output levels implies the first output values reading as 0. The driver

Add the correct silicon variant code ID (0x5) to the driver. This
new code is the 'production' variant code ID for DA9063.

This patch will remove the older variant code ID which matches the
pre-production silicon ID (0x3) for the DA9063 chip.

There is also some small amount of correction done in this patch:
it splits the revision code and correctly names it according to
the hardware specification and moves the dev_info() call before
the variant ID test.
