Convert the PCI mediatek Documentation to YAML schema to enable
validation of the supported GEN1/2 Mediatek PCIe controller.
While converting, lots of cleanup were done from the .txt with better
specifying what is supported by the various PCIe controller variant and
drop of redundant info that are part of the standard PCIe Host Bridge
schema.
To reduce schema complexity the .txt is split in 2 YAML, one for
mt7623/mt2701 and the other for every other compatible.

- where N starting from 0 to one less than the number of root ports.
-- phys: List of PHY specifiers (used by generic PHY framework).
-- phy-names : Must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the
- number of PHYs as specified in *phys* property.
-- power-domains: A phandle and power domain specifier pair to the power domain

-- bus-range: Range of bus numbers associated with this controller.
-- ranges: Ranges for the PCI memory and I/O regions.
-
-Required properties for MT7623/MT2701:
-- #interrupt-cells: Size representation for interrupts (must be 1)
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
- Please refer to the standard PCI bus binding document for a more detailed
- explanation.
-- resets: Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names: Must be "pcie-rst0", "pcie-rst1", "pcie-rstN".. based on the

-Required properties for MT2712/MT7622/MT7629:
--interrupts: A list of interrupt outputs of the controller, must have one
- entry for each PCIe port
-- interrupt-names: Must include the following entries:
- - "pcie_irq": The interrupt that is asserted when an MSI/INTX is received
-- linux,pci-domain: PCI domain ID. Should be unique for each host controller
-
-In addition, the device tree node must have sub-nodes describing each
-PCIe port interface, having the following mandatory properties:
-
-Required properties:
-- device_type: Must be "pci"
-- reg: Only the first four bytes are used to refer to the correct bus number
- and device number.
-- #address-cells: Must be 3
-- #size-cells: Must be 2
-- #interrupt-cells: Must be 1
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
- Please refer to the standard PCI bus binding document for a more detailed

-- ranges: Sub-ranges distributed from the PCIe controller node. An empty
- property is sufficient.

Introduce Airoha AN7583 SoC compatible in mediatek PCIe controller
binding.
Similar to GEN3, the Airoha AN7583 GEN2 PCIe controller require the
PBUS csr property to permit the correct functionality of the PCIe
controller.

Add support for the second PCIe line present on Airoha AN7583 SoC.
This is based on the Mediatek Gen1/2 PCIe driver and similar to Gen3
also require workaround for the reset signals.
Introduce a new bool to skip having to reset signals and also introduce
some additional logic to configure the PBUS registers required for
Airoha SoC.
