* [DM/OFW][PCI] Fix address translation and PCI resource enumeration
Rework OFW address translation to walk nested bus ranges in the correct
direction and cache "ranges" and "dma-ranges" independently. Handle PCI
three-cell addresses without treating the PCI flags cell as part of the
address, and fix CPU-to-DMA and DMA-to-CPU translation across nested
buses.
Fix PCI BAR sizing and assignment by disabling address decoding during
probing, preserving BAR attribute bits, and programming 64-bit BARs
correctly. Add device enable and disable helpers so resources and bus
mastering are enabled before driver probe.
Program bridge memory and prefetch windows while scanning downstream
buses, correctly link child buses into the PCI bus hierarchy, and avoid
unnecessary PCIe link retraining when the link is already active.
Allow host bridges without a device-tree pci-domain property by
allocating unique domains dynamically, while preserving explicit domain
assignments.
Fix MSI and MSI-X IRQ setup, rollback, vector addressing, and affinity
selection.
Add the Raspberry Pi PCI vendor ID for RP1 and other downstream devices.

Fixup fdt address reg and cells parse.
Support only option name way for earlycon.
Find the console device when using "stdout-path".

DMA and CPU address view is different, we need to convert them:
+--------+ +--------+ +---------+ +--------+
| | | | | | | |
| CPUs | | DEV0 | | IOMMU <----+ | DEV1 |
| | | | | | | | |
+----+---+ +----+---+ +----+----+ | +----+---+
| | | | |
0x200000 | 0x1000 | 0x1000 | | 0x8000 |

+-------------+-----------+ +----------+

[OFW] io ranges use ptr array to storage without ofw data
ofw data is private data for every ofw node that
the drivers of ofw node will use item.
replace the ranges supported to a ptr array.
the ptr array size is config by `RT_USING_OFW_BUS_RANGES_NUMBER`

We support OFW API to replace fdt old API, and add
IRQ, IO, Platform-Bus, CPUs ... OFW node contorl.
To support work with Device Tree or ACPI in drivers
that use IRQ, we make a programmable interrupt
controller driver's model.
