ARM: shmobile: porter: add QSPI DT support
Define the Porter board dependent part of the QSPI device node.
Add device nodes for Spansion S25FL512S SPI flash and the MTD partitions
on it.
This patch is mostly analogous to the commit f59838d44835 ("ARM:
shmobile: henninger: add QSPI DT support") as there are no differences
between the boards in this respect.
