Nobody uses the exported helper syscon_base_lookup_by_pdevname,
to lookup a syscon by device name. Let us remove it.

Rohm BD71837 is a PMIC for i.MX8MM, which is used on most boards
supported by barebox. So far, we didn't need to change PMIC
configuration after the initial setup in PBL, but to support future
debugging and development, let's port the Linux MFD driver sans the
regulators, so we get a regmap for interacting with the device.

The '_d' suffix was originally introduced in case we want to import
Linux struct device as a separate struct into barebox. Over time it
became clear that this won't happen, instead barebox struct device_d
is basically the same as Linux struct device. Rename the struct name
accordingly to make porting Linux code easier.

By default the iMX6UL is configured to output clock on the ENET1_TX_CLK
pin. Since on the Protonic PRTI6G board the PHY is actual refclock provider, we
should change the clock source to the external clock.

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.

Currently the pfuze driver is build dependent to ARCH_IMX6. To make it
possible to work with ARCH_IMX8 we move the imx6_poweroff call to an own
poweroff handler.
