dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

g. If the driver provides an ofdata_to_platdata() method, then this is
called to convert the device tree data into platform data. This should
- do various calls like fdtdec_get_int(gd->fdt_blob, dev->of_offset, ...)
+ do various calls like fdtdec_get_int(gd->fdt_blob, dev_of_offset(dev), ...)
to access the node and store the resulting information into dev->platdata.
After this point, the device works the same way whether it was bound
using a device tree node or U_BOOT_DEVICE() structure. In either case,
