[OFW] io ranges use list to storage without ofw data (#8993) 
[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`

[drivers][core] 完善设备模型 (#8384) 2024-01-09 23:10:42 +08:00
wusongjie 8aa4366cb2 Drivers: Support Open Firmware API and model of PIC 
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.
