Subject: [PATCH v2] drm/amdgpu: Enable VM_CONTEXT1_CNTL after page table addr
 is set.

In setup_vmid_config functions of all mmhubs, the CONTEXT1_CNTL reg is
enabled before related CONTEXT1_PAGE_TABLE_START_ADDR and
CONTEXT1_PAGE_TABLE_END_ADDR regs are written, which may cause
undefined behavior.

This patch enable CONTEXT1_CNTL after page table addresses are set,
so that it can ensure no undefined behavior will happen.
