Grant Likely d524dac927 dt: Move device tree documentation out of powerpc directory
The device tree is used by more than just PowerPC.  Make the documentation
directory available to all.

v2: reorganized files while moving to create arch and driver specific
    directories.

EEPROMs (I2C)
Required properties:
- compatible : should be "<manufacturer>,<type>"
If there is no specific driver for <manufacturer>, a generic
driver based on <type> is selected. Possible types are:
24c00, 24c01, 24c02, 24c04, 24c08, 24c16, 24c32, 24c64,
24c128, 24c256, 24c512, 24c1024, spd
- reg : the I2C address of the EEPROM
Optional properties:
- pagesize : the length of the pagesize for writing. Please consult the
manual of your device, that value varies a lot. A wrong value
may result in data loss! If not specified, a safety value of
'1' is used which will be very slow.
- read-only: this parameterless property disables writes to the eeprom
Example:
eeprom@52 {
compatible = "atmel,24c32";
reg = <0x52>;
pagesize = <32>;
};
