[roll] Roll fuchsia [05/nn][hdmi-dw] HdmiDw owns the controller IP MMIO region on
creation; delete HdmiBase.
Now that the HDMITX MMIO region is separated to controller IP region
and top-level region, only HdmiDw will read/write on the controller
region.
To simplify the MMIO access model, we make the following changes:
- We move the ownership of controller IP MMIO buffer to HdmiDw.
This removes all the indirections for HdmiDw to access register
contents.
- HdmiDw doesn't need to use HdmiBase to read/write IP registers.
It's safe to delete the HdmiBase class. We delete the HdmiBase
class in this change.
- We also remove the locks on the MMIOs in the aml-hdmi driver.
Both aml-hdmi and hdmi-dw have access to only one register region.
Test: Modified aml-hdmi-test and hdmi-dw-test to reflect the new change.
Test: "display-tool squares 1" works on:
- Surenoo SUR480480Y021
- Amelin AML028-30MB-1
- MIMO 10" display
