If we are softbooting another kernel using kexec, DMA controller state is not
known when we are performing omap_init_dma(). It is possible that some DMA
channels are already active. For example after kexec we get:

<4>IRQ 0020 for non-allocated DMAchannel 5
<4>IRQ 0020 for non-allocated DMAchannel 5
<4>IRQ 0020 for non-allocated DMAchannel 5
<4>IRQ 0020 for non-allocated DMAchannel 5
<4>IRQ 0020 for non-allocated DMAchannel 5

To prevent any weird things happening, we disable all channel interrupts during
init.

I believe the VMMC2 constraints must be the same than with VAUX3. Older
boards are using TWL4030 VMMC2 supply for internal MMC whereas newer are
using VAUX3 that has more limited constraints defined in this same file.

More over, the VMMC2 supply is used also for analog audio domain and the
miminum analog voltage of the TLV320AIC34 codec is 2.7 V.

To combine these two facts, the patch changes supply name to V28_A as the
newer boards register VMMC2_30 for VAUX3 and uses the same constraints than
VAUX3 since those constraints are ok for the TLV320AIC34.

Ensure GPIO debounce clocks are disabled when idle.  Otherwise,

Signed-off-by: NKevin Hilman <khilman@deeprootsystems.com>

Currently, the GPIO 'prepare' hook is only called when going to
off-mode, while the function is called 'prepare_for_retention.'  This
patch renames the function to 'prepare_for_idle' and calls it for any
powersate != PWRDM_POWER_ON passing in the powerstate.

The hook itself is then responsible for doing various preparation
based on the powerstate.
