Yong Wu 596f59d336 iommu/mediatek: Add mutex for m4u_group and m4u_dom in data 
[ Upstream commit 0e5a3f2e63 ]

Add a mutex to protect the data in the structure mtk_iommu_data,
like ->"m4u_group" ->"m4u_dom". For the internal data, we should
protect it in ourselves driver. Add a mutex for this.
This could be a fix for the multi-groups support.
