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

| Address BUS |

[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.
