        MIPS: dts: use physical addresses (as Linux does)

        With IOMEM() adapted for MIPS we can use physical addresses
        in device tree reg property.

has switched MIPS dts files to physical addresses usage.

The patch was tested on qemu, but qemu malta board is tolerant
of using physical addresses for accesing to device
(Ingenic JZ4755 and JZ4780 processors are tolerant too!).
But other CPUs (e.g. Loongson LS1B) can throw an exception
in this situation.

Additional physical address to virtual address translation
on MIPS is needed.

We already have this in include/common.h

    #if defined(CONFIG_MIPS)
    #include <asm/addrspace.h>

    #define IOMEM(addr) ((void __force __iomem *)CKSEG1ADDR(addr))
    #else
    #define IOMEM(addr) ((void __force __iomem *)(addr))
    #endif

So use IOMEM() to fix dev_request_mem_region() return value.
