Subject: [PATCH v3] Add MediaTek MT6779 devapc driver 

These patch series introduce a MediaTek MT6779 devapc driver.

MediaTek bus fabric provides TrustZone security support and data protection to prevent slaves from being accessed by unexpected masters.
The security violation is logged and sent to the processor for further analysis or countermeasures.

Any occurrence of security violation would raise an interrupt, and it will be handled by mtk-devapc driver.
The violation information is printed in order to find the murderer.

changes since v2:
- pass platform info through DT data.
- remove unnecessary function.
- remove slave_type because it always equals to 1 in current support SoC.
- use vio_idx_num instread of list all devices' index.
- add more comments to describe hardware behavior.

changes since v1:
- move SoC specific part to DT data.
- remove unnecessary boundary check.
- remove unnecessary data type declaration.
- use read_poll_timeout() instread of for loop polling.
- revise coding style elegantly.
