2mA drive strength is not enough when we connect multiple i2c devices

This issue was detected when multiple i2c devices connected on the other side
of level shifters on Linaro sensor board. Maxing up to 16mA made i2c much stable.

drm/msm: mdp4 lvds: Check the panel node in detect_panel()
This patch checks if the panel node is disabled in DT or not, this would
let us return proper error code so that the driver could stop panel
specific intialization.
drm/msm: mdp4 lvds: continue if the panel is not connected
Two issues:
1> Intializing panel specific bits without actual panel presence.
2> Bailing out if the detect_panel() return -ENODEV.
With the existing code if detect_panel() returns an error code the
driver would bail out without doing anything, However it could continue
intializing hdmi related things. This patch adds two things.
1> moves the panel specific intialization only if the panel is detected
2> let the driver continue with hdmi intialization if detect_panel()
return -ENODEV.
This patch adds panel picker support to simple-panel.
The idea of panel picker is to select the correct panel timings if it
supports probing edid via DDC bus, edid contains manufacture ID
and Manufacturer product code, so it can match against the panel_picker
entries to get the correct panel timings.
From DT point of view the panel picker uses generic compatible string
"panel-simple", keeping the panel specific compatible strings still
supported.
Panels can be static entry in the DT, but practically development boards
like IFC6410 where developers can connect any LVDS panel which makes it
difficult to maintian the dt support for those panels in dts file.
With this dynamic probing via panel picker makes it easy to support such
use-cases.
This patch also adds panel presence detection based, if there is no
panel detected or panel picker could not find the panel then the driver
would mark the panel DT node as disabled so that the drm driver would
be able to take right decision based on that panel node status.
This patch adds support to get edid way early before the connector is
created, this is mainly used for panel drivers to auto-probe the panel
based on the vendor and product id from EDID.
PCI: designware: add memory barrier after enabling region
Add 'write memory' barrier after enable region in PCIE_ATU_CR2
register. The barrier is needed to ensure that the region enable
request has been reached it's destination at time when we
read/write to PCI configuration space.
Without this barrier PCI device enumeration during kernel boot
is not reliable, and reading configuration space for particular
PCI device on the bus returns zero aka no device.
As part of Rob Clarks cleanup one of the flags have been renamed in
header which introduced a compilation failure.
