Compared to the "old" driver:
- Each device must assign a pinctrl setting to the SPI node to allow the
new SPI driver to configure the SPI pins.
While here we are also using separate input and output settings so we
are independent of whether the bootloader configures the pins correctly.
- We use the new "compatible" strings to make the driver choose the
correct number of chip-selects for each SoC.
- The new driver starts counting the chip-selects at 1 (instead of 0, like
the old one did). Thus we have to adjust the devices accordingly.

This allows devices to use SPI without having to re-define (and thus
duplicating) the whole SPI node.
By default SPI is disabled (as before) because only few devices need it.

After the latest pinctrl backports there are only 50 (instead of 56 as
before) GPIOs/pins exported (thus the first GPIO on VRX200 SoCs is now
462, before it was 456). This means that any hardcoded GPIOs have to be
adjusted.
This broke the PCIe driver (which seems to be the only driver which uses
hardcoded GPIO numbers), it only reports:
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
pcie_rc_initialize link up failed!!!!!
To prevent more of these issues in the future we remove the hardcoded
PCIe reset GPIO definition and simply pass it via device-tree (like the
PCI driver does).

These were introduced in upstream commit
be14811c03cf "pinctrl/lantiq: introduce new dedicated devicetree
bindings" and finally allow us to use the individual pins within our dts
(for example spi_clk, etc.).
Please note that this changes the number of GPIOs which are available for
some SoCs. VRX200 SoCs for example only have 50 pins, but previously 56
pins were exposed. This means that all places which are using hardcoded
GPIO numbers (which are not passed via device-tree) need to be adjusted
(because the first GPIO number is now 462, instead of 456).

linux 4.4 (since commit 08b3c894e56580b8ed3e601212a25bda974c3cc2
"MIPS: lantiq: Disable xbar fpi burst mode") requires that the xbar is
defined in the .dts of vrx200 (VR9) SoCs.

Newer DSL driver versions depend on the address information.

Here the device tree entry for ifxhcd is listed as compatible with one
supported in dwc2 (after patching the dwc driver appropriately).
A second entry is added to support the second core of the hcd. This
entry is listed to be compatible with only dwc2. Done this way there
should be backwards support for both hcd drivers (ltq-hcd and dwc2)
