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.

When probing, regmap_register_patch() will bypass the cache and perform
i2c writes for the given patches. It is thus unnecessary to manually set
the TWL6040_REG_ACCCTL register just before, as it will be done when
registering the twl6040_patch.

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
so can't be aware of set values GPIOs by bootloader or BIOS.

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.

During probe the driver allocates two dummy I2C devices for subchips in
function pm800_pages_init(). Additionally this function allocates
regmaps for these subchips. If any of these steps fail then these dummy
I2C devices are not freed and resources leak.
On pm800_pages_init() fail the driver must call pm800_pages_exit() to
unregister dummy I2C devices.

Three of the PMIC registers have some bits that are changed
autonomously by the PMIC itself (some time) after being set
by some component driver of the DA9052 PMIC and hence they
need to be marked as volatile so that the regmap API will
not cache their values.

During probe the driver allocates dummy I2C devices for MUIC and haptic
with i2c_new_dummy() but it does not check the return value of this
calls.
In case of error (i2c_new_device(): memory allocation failure or I2C
address cannot be used) this function returns NULL which is later used
by devm_regmap_init_i2c() and i2c_unregister_device().
If i2c_new_dummy() fails for MUIC or haptic devices, fail also the probe
for main MFD driver.

This changes the following mechanisms in the TC3589x device tree
probing path:
- Use the .of_match_table in struct device_driver to match the
device in the device tree.
- Add matches for the proper compatible strings "toshiba,..."
and all sub-variants, just as is done for the .id matches.
- Move over all the allocation of platform data etc to the
tc3589x_of_probe() function and follow the pattern of passing
a platform data pointer back, or an error pointer on error,
as found in the STMPE driver.
- Match the new (proper) compatible strings for the GPIO and
keypad MFD cells.
- Use of_device_is_compatible() rather than just !strcmp()
to discover which cells to instantiate.
