memory: omap-gpmc: fixup wrongly hierarchy of the sub-devices
Commit Message
On TI-AM335x，FPGA under GPMC local-bus can not work on 6.x kernel.
GPMC <--> FPGA <--> sub-devices....
I found that the platform sub-devices are in wrongly organized
hierarchy. The grandchildren are now under the GPMC device directly,
not under it's father(FPGA).
