Description

This PR includes the following changes

• I noticed that we were making use of r_i2c to communicate with AXP chip for Orange Pi lite2 and one plus in linux kernel, but were using r_rsb in u-boot. Made this consistent by porting the patch used in sunxi kernel to u-boot.
• Moved to board specific crust config for Orange Pi 3, lite2 and one plus. The difference from previous configuration is that crust will now be aware of presence of AXP power chip present on the board and hence should be able to lower the power usage further during sleep or shutdown state
• Enabled kernel module for Hantro G2 video codec block available on H6 boards. Should allow faster video decoding in some video player. With this change chromium browser now detects presence of hardware acceleration in the hardware. Still doesn't uses the same for some reason. Fixing hardware acceleration in chromium will follow in another PR later once I have it working.
• Last one is just cosmetics change, where I enabled bootsplash for Orange Pi 3 LTS board.

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration.

• [X] Checked that Hantro G2 driver loads on Orange Pi 3 LTS. Also the bootsplash is visible while booting the desktop
• [X] I gave a build with the crust and u-boot changes from this PR and a potential ethernet fix for one plus to @EvilOlaf. He confirmed that device boots and reboots fine. So crust and u-boot changes are not causing any issues. Once I have a working ethernet fix, it will follow in different PR.
