OMAP4: hwmod data: Add clock domain attribute

In OMAP PRCM terminology, the clock domain is defined as a group of IPs
that share some clocks and most of the time an interface clock.
Every IP does belong to a clockdomain.
For the moment the clock domain attribute is affected to a clock node.
The issue with that approach, is that a clock might or not belong to a
clock domain. Moreover during module transition, it is up to a module
to handle properly the clock domain state and not to a clock node.

Create a clkdm_name attribute to provide this information per hwmod.

Populate this attribute for every OMAP4 hwmod entries.

Future cleanup series with remove that information from the OMAP4 clock
when it is relevant.

errors reporting 32-bit access to I2C peripheral unit registers
that are documented to be 8 or 16-bit only[1][2]

The I2C driver is blameless as it wraps its accesses in a
function using __raw_writew and __raw_readw, it turned out it
is the hwmod stuff.

However the hwmod code already has a flag to force a
perhipheral unit to only be accessed using 16-bit operations.

This patch applies the 16-bit only flag to the 2430,
OMAP3xxx and OMAP44xx hwmod structs.  2420 was already
correctly marked up as 16-bit.

The 2430 change will need testing by TI as arranged
in the comments to the previous patch version.

When the 16-bit flag is or-ed with other flags, it is placed
first as requested in comments.

OMAP4: hwmod data: Change DSS main_clk scheme

Currently using pm_runtime with DSS requires the DSS driver to enable
the DSS functional clock before calling pm_runtime_get(). That makes it
impossible to use pm_runtime in DSS as it is meant to be used, with
pm_runtime callbacks.

This patch changes the hwmod database for OMAP4 so that enabling the
hwmod via pm_runtime will also enable the DSS functional clock, allowing
us to use pm_runtime properly in DSS driver.

The DSS HWMOD side is not really correct, not before nor after this
patch, and getting DSS to retention will probably not work currently.
However, it is not supported in the mainline kernel anyway, so this
won't break anything.

So this patch allows us to write the pm_runtime adaptation for the DSS
driver the way it should be done, and the HWMOD/PM side can be fixed
later.

OMAP4: powerdomain data: Remove unsupported MPU powerdomain state

On OMAP4430 devices, because of boot ROM code bug, MPU OFF state can't
be attempted independently. When coming out of MPU OFF state, ROM code
disables the clocks of IVAHD, TESLA which is not desirable. Hence the
MPU OFF state is not usable on OMAP4430 devices.

OMAP4460 onwards, MPU OFF state will be descoped completely because
the DDR firewall falls in MPU power domain. When the MPU hit OFF state,
DDR won't be accessible for other initiators. The deepest state supported
is open switch retention (OSWR) just like CORE and PER PD on OMAP4430.

So in summary MPU power domain OFF state is not supported on OMAP4
and onwards designs. Thanks to new PRCM design, device off mode can
still be achieved with power domains hitting OSWR state.

Above makes access to GPMC unpredictable during the execution, so it's

control.

changed values for .devsize in nand platform data, now we have to pass
NAND_BUSWIDTH_16 instead of '1' to select 16bit NAND.

Update pandora's platform data accordingly, also specify appropriate
