Add support for partition table defined in Device Tree. Similar to how it's done with MTD, add support for defining a fixed partition table in device tree. A common scenario for this is fixed block (eMMC) embedded devices that have no MBR or GPT partition table to save storage space. Bootloader access the block device with absolute address of data. This is to complete the functionality with an equivalent implementation with providing partition table with bootargs, for case where the booargs can't be modified and tweaking the Device Tree is the only solution to have an usabe partition table. The implementation follow the fixed-partitions parser used on MTD devices where a "partitions" node is expected to be declared with "fixed-partitions" compatible in the OF node of the disk device (mmc-card for eMMC for example) and each child node declare a label and a reg with offset and size. If label is not declared, the node name is used as fallback. Eventually is also possible to declare the read-only property to flag the partition as read-only.
