Changes v3->v4
- rebased to linux-3.10-rc3
- updated newly supported DT properties based on following commits
[d36b4cd] jon-hunter@ti.com ARM: OMAP2+: Add additional GPMC timing ...
[8c8a777] jon-hunter@ti.com ARM: OMAP2+: Add function to read GPMC ...
[9f83315] jon-hunter@ti.com ARM: OMAP2+: Add variable to store number
Changes v2->v3
- rebased to linux-3.9-rc8
- AM335x-evm.dts: moved GPMC pin-mux config to nand node
Changes v1->v2
- Change number of chip select to 7
- Replace <xx> literals to 52
- remove tab
