mfd: Make twl4030 SIH SPARSE_IRQ capable
twl4030 is using a two level irq controllers infrastruture.
So far, only the first level was using dynamic irq_desc allocation
to be able to have irq_domain support for device tree.
There is a need to allocate separate irq_descs for the SIH too to
avoid hacking the first level with interrupts from the second level.
Add an irq_base parameter to allow the caller to provide the base from
pdata or from dynamic allocation.
Affect TWL4030_NR_IRQS to the twl-core IRQs only.
Moreover that will allow the extraction of the of_node pointer for further
Device Tree conversion.

mfd: Move twl-core IRQ allocation into twl[4030|6030]-irq files
During DT adaptation, the irq_alloc_desc was added into twl-core, but
due to the rather different and weird IRQ management required by the twl4030,
it is much better to have a different approach for it.
The issue is that twl4030 uses a two level IRQ mechanism but handles all the
PWR interrupts as part of the twl-core interrupt range. It ends up with a
range of 16 interrupts total for CORE and PWR.
The other twl4030 functionalities already have a dedicated driver and thus
their IRQs and irqdomain can and should be defined localy.
twl6030 is using a single level IRQ controller and thus does not require any
trick.
Move the irq_alloc_desc and irq_domain_add_legacy in twl4030-irq and
twl6030-irq.
Allocate together CORE and PWR IRQs for twl4030-irq.

mfd: Clear twl6030 IRQ status register only once
TWL6030 family of PMIC use a shadow interrupt status register
while kernel processes the current interrupt event.
However, any write(0 or 1) to register INT_STS_A, INT_STS_B or
INT_STS_C clears all 3 interrupt status registers.
Since clear of the interrupt is done on 32k clk, depending on I2C
bus speed, we could in-adverently clear the status of a interrupt
status pending on shadow register in the current implementation.
This is due to the fact that multi-byte i2c write operation into
three seperate status register could result in multiple load
and clear of status and result in lost interrupts.
Instead, doing a single byte write to INT_STS_A register with 0x0
will clear all three interrupt status registers without the related
risk.

Merge tag 'fixes-3.3-rc4' of git://git./linux/kernel/git/arm/arm-soc
These are the bug fixes that have accumulated since 3.3-rc3 in arm-soc.
The majority of them are regression fixes for stuff that broke during
the merge 3.3 window.
The notable ones are:
* The at91 ata drivers both broke because of an earlier cleanup patch that
some other patches were based on. Jean-Christophe decided to remove
the legacy at91_ide driver and fix the new-style at91-pata driver while
keeping the cleanup patch. I almost rejected the patches for being too
late and too big but in the end decided to accept them because they
fix a regression.
* A patch fixing build breakage from the sysdev-to-device conversion
colliding with other changes touches a number of mach-s3c files.
*
b0654037 "ARM: orion: Fix Orion5x GPIO regression from MPP cleanup"
is a mechanical change that unfortunately touches a lot of lines
that should up in the diffstat.
