mfd: syscon: implement device_node_to_regmap ...

Extend our syscon API with a device_node_to_regmap function that has the
same semantics as upstream:

|
| mfd/syscon: Add device_node_to_regmap()
|
| device_node_to_regmap() is exactly like syscon_node_to_regmap(), but it
| does not check that the node is compatible with "syscon", and won't
| attach the first clock it finds to the regmap.
|
| The rationale behind this, is that one device node with a standard
| compatible string "foo,bar" can be covered by multiple drivers sharing a
| regmap, or by a single driver doing all the job without a regmap, but
| these are implementation details which shouldn't reflect on the
| devicetree.

PCI: imx6: Add proper i.MX6+ reset sequence ...

I.MX6+ version of the silicon exposed PCIe core's reset signal as a bit
in one of the control registers. As a result using old, pre-i.MX6+,
reset sequence on i.MX6+ leads to Barebox hanging during startup. Using
exposed reset bit instead solves the problem.

mfd: mc13xxx: Allow to set callback for mc13xxx ...

Some boards have to initialize the PMIC before other devices can
be initialized. This requires three levels of initcalls: one level
in which the PMIC is probed, one in which the board can call mc13xxx_get()
and the third one to initialize the PMIC dependent devices.

Allow to register a callback which is called once the PMIC is initialized.
This way mc13xxx_get() is no longer necessary and the number of required
initcalls levels is reduced to two.
