The Designware controller has common registers to set number of fast
training sequence ordered sets. The Artpec6, Intel, and Tegra driver
initialize these register fields. Let's move the initialization to the
common setup code and drivers just have to provide the value.
There's a slight change in that the common clock mode N_FTS field is
now initialized. Previously only the Intel driver set this. It's not
clear from the code if common clock mode is used in the Artpec6 or Tegra
driver. It depends on the DWC configuration. Given the field is not
initialized while the others are, it seems unlikely common clock mode
is used.

'max_width' is read, but never used, so let's remove it.

The PCI_CAP_ID_EXP offset is only needed by intel_pcie_link_setup(), so
let's retrieve it there and avoid storing the offset.

A driver doesn't need to check for DT 'device_type' property, so let's
remove the check.

The Intel driver is the only one to set PORT_LINK_DLL_LINK_EN. The
default value is set and it seems pretty certain that enabling link
initialization is always required. Maybe it could just be dropped from
the Intel driver, but lets move setting it into the common code to be
sure.

Use devm_platform_ioremap_resource_byname() to simplify the code
since it contains platform_get_resource_byname() and
devm_ioremap_resource() respectively.

Add support to PCIe RC controller on Intel Gateway SoCs.
PCIe controller is based of Synopsys DesignWare PCIe core.
Intel PCIe driver requires Upconfigure support, Fast Training
Sequence and link speed configurations. So adding the respective
helper functions in the PCIe DesignWare framework.
It also programs hardware autonomous speed during speed
configuration so defining it in pci_regs.h.
Also, mark Intel PCIe driver depends on MSI IRQ Domain
as Synopsys DesignWare framework depends on the
PCI_MSI_IRQ_DOMAIN.
