mtd: m25p80: Fix Kconfig dependencies ...

The m25p80 driver now depends on MTD_SPI_NOR which is disabled in all
defconfigs, so this effectively disables the m25p80 driver in all
defconfigs. Fix this by selecting MTD_SPI_NOR which is library code
without further dependencies. Also let m25p80 depend on SPI because
it needs the SPI code and won't link without it.

i2c: omap: fix i2c bus number output ...

When probing from devicetree, the output for several i2c host
controllers prints out a bus number of -1:

i2c-omap 44e0b000.i2c: bus -1 rev0.11 at 400 kHz
i2c-omap 4802a000.i2c: bus -1 rev0.11 at 400 kHz
i2c-omap 4819c000.i2c: bus -1 rev0.11 at 400 kHz

The call to i2c_add_numbered_adapter() in probe finds out the next free
bus number, so we move the output to a location where the number is
already determined.

Abolish cpu_read* and cpu_write* accessors ...

Commit 2e6a88f2101d (add cpu native ordered io accessors) introduced
these macros and then commit be57f20cdd7d (Fix big endian MMIO
primitives) figured out they are equivalent to __raw_{read,write}*.

They turned out unnecessary after all.  Anyway, most source files
use __raw_read* and __raw_write*.

Let's replace a few remaining references and abolish them.

This patch improves the backend property, it can be either a phandle or a

dereferenced and the resulting of_path is saved in the state context. In a
later patch it will be used to generate a phandle reference to the backend
during DT fixup.

net: dm9k: fix reset routine ...

Based on Linux's commit:

    commit 09ee9f8

        dm9000: Implement full reset of DM9000 network device

        A Davicom application note for the DM9000 network device recommends
        performing software reset twice to correctly initialise the device.
        Without this reset some devices fail to initialise correctly on
        system startup.

N.B. DM9000B on MIPS Creator CI20 board needs additional workaround
(see the 'Make all GPIO pins outputs' and 'Power internal PHY' lines).

This workaround was taken from this U-boot's commit:

    commit fbcb7ec
    Author: Remy Bohmer <linux@bohmer.net>
    Date:   Tue Jun 3 15:26:24 2008 +0200

        DM9000: Improve eth_reset() routine

        According to the application notes of the DM9000 v1.22 chapter 5.2 bullet 2, the
        reset procedure must be done twice to properly reset the DM9000 by means of software.
        This errata is not needed anymore for the DM9000A, but it does not bother it.

        This change has been tested with DM9000A, DM9000E, DM9000EP.
