arm/versatile: Add device tree support For testing the dt work, define a dt-enabled versatile platform. This patch adds a new versatile platform for when using the device tree. Add platform and amba devices are discovered and registered by parsing the device tree. Clocks and initial io mappings are still configured statically. This patch still depends on some static platform_data for a few devices which is passed via the auxdata structure to of_platform_populate(), but it is a viable starting point until the drivers can get all configuration data out of the device tree.

SMSC LAN91c111 Ethernet mac
Required properties:
- compatible = "smsc,lan91c111";
- reg : physical address and size of registers
- interrupts : interrupt connection
Optional properties:
DT: net: document Ethernet bindings in one place This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save some of the trouble of documenting several properties over and over in each binding document, instead only making reference to the main file. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.

net: smc91x: Fix device tree based configuration so it's usable Commit 89ce376c6bdc (drivers/net: Use of_match_ptr() macro in smc91x.c) added minimal device tree support to smc91x, but it's not working on many platforms because of the lack of some key configuration bits. Fix the issue by parsing the necessary configuration like the smc911x driver is doing. As most smc91x users seem to use 16-bit access, let's default to that if no reg-io-width is specified.

- reg-io-width : Mask of sizes (in bytes) of the IO accesses that
are supported on the device. Valid value for SMSC LAN91c111 are
1, 2 or 4. If it's omitted or invalid, the size would be 2 meaning
16-bit access only.
net: smc91x: Fix gpios for device tree based booting With legacy booting, the platform init code was taking care of the configuring of GPIOs. With device tree based booting, things may or may not work depending what bootloader has configured or if the legacy platform code gets called. Let's add support for the pwrdn and reset GPIOs to the smc91x driver to fix the issues of smc91x not working properly when booted in device tree mode. And let's change n900 to use these settings as some versions of the bootloader do not configure things properly causing errors.
