tegra power: Fix gart suspend/resume operations
Apply proper barriers to suspend/resume operations.
The dmb() in suspend is required to prevent a race
between the next ENTRY_ADDR write and the previous
ENTRY_DATA read. The dsb+outer_sync() in resume()
is needed to ensure that the writes and reads occur
as expected.
