OMAPDSS: DISPC: Use FIR filters other than M19

Pass correct arguments to FIR filter selection.  Previously we
always ended up selecting M19 5-tap filter.

This should improve image quality of scaled layers.

TWL6032: Fix missing VBUS interrupts after OTG-cable insertion

After OTG-cable is plugged there is no possible to connect PC
to the device (not works adb etc) because VBUS interrupts are
missed. This patch fix it.

PM: OPP: Add opp_find_volt_floor/ceil functions

Add functions to find OPP by voltage value
in the same way as it is made for frequency.

OMAP3+: DVFS: Use opp_find_volt functions instead of _volt_to_opp

Currently OMAP DVFS framework uses _volt_to_opp() function
to find OPP by voltage, but it is made in a hacky way,
because it doens't have access to list of OPP.

That function has a few important limitations:

1. It assumes that each OPP has an unique frequency value
   so it skips next OPPs with the same frequency.
   For example OMAP4 L3 bus has several OPPs which have
   same frequency, but different voltage values.
   So the function is not able to find correct OPP for L3.

2. Rounding direction is not predictable.
   By default function rounds up, but if requested voltage is
   higher that highest OPP voltage, then function rounds down.
   In most places where the function is used, code expect that
   it rounds down which is opposite to default behavior.

The patch change _volt_to_opp() function by opp_find_volt_ceil()
and opp_find_volt_floor() functions.

OMAP4470: OPP/voltage: Add CORE OPP100 to High Perf CORE OPP set

Initially 4470 High Performance CORE OPP set didn't have OPP100 defined.
That's why when some devices need OPP100 VDD_CORE voltage level
to work at higher frequency they have to scale L3 to OPP-OV.

To fill a gap between OPP50 and OPP-OV a new OPP100 have been added.
It has OPP100 voltage level but keeps L3 frequency at 116MHz.

Both 4470's OPP sets share same OPP depencensies tables,
so a new OPP100H is defined to maintain correct depencencies
in both OPP sets.

OMAP4: OPP: Add DSS OPPs

To generate pixel clock rate higher than 93MHz
DSS has to scale VDD_CORE to at least OPP100 level.

This patch adds two DSS OPPs, for DSS to be able
to control minimum VDD_CORE level.

OMAPDSS: DSS: Scale DSS OPP according to pixel clock rate

Before enabling pixel clock DSS should set its OPP

When pixel clock is disabled DSS can set the lowest OPP.

OMAPDSS: DSS: Relax L3 bus bandwidth constraint

In a current codebase L3 BW constraint is set if
any display has resution higher or equal FullHD.

Estimated available DSS bandwidth on L3@OPP50 is ~800MB/s.
It is approximately 3 WXGA layers or almost 1.5 FullHD layers at
60fps rate.

This patch relaxes L3 BW constraint and set it only
if current overlays' configuration needs higher BW.

ARM: OMAP: HS USB Host: fix unbalanced pm calls

There is an issue with unbalanced pm calls.
Only EHCI or only OHCI works good but not together.
Issue appears when OHCI suspends whereas EHCI is active
or vice versa - anyway all HSUSBHOST goes to suspend.
This patch fixes this issue.
