Oh I cherry-pick the commit of syscon node and it also include the MMC node.
I will remove the MMC node. 
I used dtbs_check and get the error 'should not be valid under {'type': 'object'}',
If I move this node out of the 'soc' node, the dtbs_check will be pass.
Is it OK to move the PLL node out of the 'soc' node? Thanks.
