ARM: OMAP2+: PRM/CM: Move the stubbed prm and cm functions to prcm.c file and make them __weak

Some prm and cm registers read/write and status functions
are built only for some custom OMAP2+ builds and are stubbed
in header files for other builds under ifdef statements.
But this results in adding new CONFIG_ARCH_OMAPXXX
checks when SOCs are added in the future. So move them
to a common place for OMAP2+ and make them 'weak' implementations.

This way no new ifdefs would be required in the future and also
cleans up the existing code.

ARM: OMAP2+: hwmod code: add support to set dmadisable in hwmod framework

The DMADISABLE bit is a semi-automatic bit present in sysconfig register
of some modules. When the DMA must perform read/write accesses, the
DMADISABLE bit is cleared by the hardware. But when the DMA must stop for power
management, software must set the DMADISABLE bit back to 1.

In cases where the ROMCODE/BOOTLOADER uses dma, the hardware clears the
DMADISABLE bit (but the romcode/bootloader might not set it back to 1).
In order for the kernel to start in a clean state, it is
necessary for the kernel to set DMADISABLE bit back to 1 (irrespective
of whether it's been set to 1 in romcode or bootloader).

During _reset of the (hwmod)device, the DMADISABLE bit is set so that it
does not prevent idling of the system. (NOTE: having DMADISABLE to 0,
prevents the system to idle)

DMADISABLE bit is present in usbotgss module of omap5.

regulator: ad5398: Fix min/max current limit boundary checking

It is ok to request current limit with min_uA < chip->min_uA and
max_uA > chip->max_uA.

We need to set min_uA = chip->min_uA if (min_uA < chip->min_uA),
this ensures the equation to calcuate selator does not return negative number.

Also set max_uA = chip->max_uA if (max_uA > chip->max_uA), as suggested by
Sonic.

ARM: at91: fix new build errors

MULTI_IRQ_HANDLER and SPARSE_IRQ are now required everywhere because
mach/irqs.h and mach/entry-macros.S are gone but the symbols are
only selected for AT91SAM9, not for the NOMMU parts.

A few files now need to include linux/io.h directly, which used to
be included through other headers that have changed.

The new at91_aic_irq_priorities variable is only used with CONFIG_OF
enabled and should not be visible otherwise.
