OMAP2+: voltage: reorganize, split code from data
This is a first pass at reorganizing mach-omap2/voltage.c:
- Separate almost all of the data from the code of mach-omap2/voltage.c.
The code remains in mach-omap2/voltage.c. The data goes into one
of several places, depending on what type of data it is:
The ultimate goal is for all this data to be autogenerated, the same
way we autogenerate the rest of our data.
- Separate VC and VP common data from VDD-specific VC and VP data.
- Separate common voltage.c code from SoC-specific code; reuse common code.
- Reorganize structures to avoid unnecessary memory loss due to unpacked
fields.
There is much left to be done. VC code and VP code should be separated out
into vc*.c and vp*.c files. Many fields in the existing structures are
superfluous, and should be removed. Some code in voltage.c seems to be
duplicated; that code should be moved into functions of its own. Proper
voltage domain code should be created, as was done with the powerdomain
and clockdomains, and powerdomains should reference voltagedomains.

OMAP2/3: VENC hwmod: add OCPIF_SWSUP_IDLE flag to interface
According to the hwmod interface data, the DSS submodule "VENC" uses a
clock, "dss_54m_fck"/"dss_tv_fck", which the PRCM cannot autoidle. By
default, the hwmod code assumes that interface clocks can be autoidled
by the PRCM. When the interface clock can't be autoidled by the PRCM,
those interfaces must be marked with the OCPIF_SWSUP_IDLE flag.
Otherwise, the "interface clock" will always have a non-zero use
count, and the device won't enter idle. This problem was observed on
N8x0.
Fix the immediate problem by marking the VENC interface with the
OCPIF_SWSUP_IDLE flag. But it's not clear that
"dss_54m_fck"/"dss_tv_fck" is really the correct interface clock for
VENC. It may be that the VENC interface should use a
hardware-autoidling interface clock. This is the situation on OMAP4,
which uses "l3_div_ck" as the VENC interface clock, which can be
autoidled by the PRCM. Clarification from TI is needed.

OMAP2+: omap_device/clock: Do not expect an entry in clkdev for opt_clks
The _add_optional_clock_alias function expects an entry
already existing in the clkdev table in the form of
<dev-id=NULL, con-id=role> which might not be the case
always.
Instead, just check if an entry already exists in clkdev
in the <dev-id=dev_name, con-id=role> form, else go ahead
and add one.
Remove any assumption of an entry already existing in clkdev
table in any form.
Since this means, adding a new entry in clkdev if it does
not already exist, and not really adding an 'alias',
also rename the function name
(s/_add_optional_clock_alias/_add_optional_clock_clkdev)

OMAP: adapt hsmmc to hwmod framework
OMAP2420 platform consists of mmc block as in omap1 and not the
hsmmc block as present in omap2430, omap3, omap4 platforms.
Removing all base address macro defines except keeping one for OMAP2420 and
adapting only hsmmc device registration and driver to hwmod framework.
Changes involves:
1) Remove controller reset in devices.c which is taken care of
by hwmod framework.
2) Using omap-device layer to register device and utilizing data from
hwmod data file for base address, dma channel number, Irq_number,
device attribute.

The MMC controller on the OMAP2420 is different from those
on the OMAP2430, OMAP3 and OMAP4 families - all of the latter

on OMAP1 chips.
Currently, the n8x0 is the only OMAP2420 platform supported
in mainline which registers the MMC controller. Upcoming
changes to register the controllers using hwmod data are
