Shengjiu Wang 26279c8d5e bus: imx-aipstz: set default value for opacr registers ...

The sdma script app_2_mcu needs the permission to access the peripheral
devices:

1) SDMA2 transactions are set to user-mode in this particular case.
2) This type of script doesn't use the peripheral interface (connected
directly to SPBA), but it uses the peripheral DMA interface, then the
SDMA2-issued transactions are subjected to AIPSTZ5's security-related
checks.

So need to clear the Supervisor Protect bit of SPBA2, otherwise the sdma
script can't work. As the imx-aipstz is a common driver for all aips bus,
so set default value (zero) for all opacr registers.
