Do dma sync after sg table created during ion alloc.
Since dma sync api requires a device, this patch also create a platform
device for ion.
The sg_phys will be filled after buffer mapped, but someone may need to
do sync without map/unmap operation, this patch also fills the sg_phys
after the sg_table created.

This reverts commit 6a40ead69f.
The old patch only do sync for pages first allocated from system to page
pools which have memset operation.
In that case, the sg table hasn't been created, so the sg_phy should be
filled extra.
After this revert, a new patch will push to do sync after sg table
created, and use a common device from ion driver, which is required by
dma_sync api.

Now we use U-Boot to write the MAC address into DTB, to
solve the problem of getting the MAC address in the vendor
partition too late at the kernel level, so the Ethernet
alias is added for U-Boot to quickly find the gmac DTB node.
