Adopt the Linux DT bindings. This also fixes an issue
with the indaddrtrig register on the Cadence QSPI
device being programmed with the wrong value for the
socfpga arch.

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.

Move the code to read the "sram-size" property into the other code
that reads properties from the node, rather than the SF subnode.
