[PATCH v4 17/25] net: mediatek: remap iobase address

[Weijie Gao <weijie.gao@mediatek.com>]

The iobase address from dts node is actually physical address. It's
identical to the virtual address in ARM platform. This is ok because this
driver was used only by ARM platforms (mt7622/mt7623 ...).

But now this driver will be used by mt7621 which is a MIPS SoC. For MIPS
platform the physical address space is mapped to KSEG0 and KSEG1 and this
makes the virtual address apparently not idential to its physical address.

To solve this issue, this patch replaces dev_read_addr with dev_remap_addr
to get the remapped iobase address.
