[PATCH] arm64: defconfig: enable further Rockchip platform drivers

[Nicolas Frattaroli]

The RK3588 SoC, and its sibling, the RK3588S, are supported by mainline
Linux. However, some of its SoC drivers are currently not enabled in the
arm64 defconfig.

Enable rockchip-dfi, rockchip-rga, and the Rockchip specific extensions
to Hantro as modules.

These drivers are also used on other Rockchip SoCs that mainline
supports, notably RK3566/RK3568, as well as RK3399.

Personally I don't think the first paragraph adds much, so I'd drop it.
 
Also I feel like you're missing the most important information here,
which is what these modules are used for, so I'd focus on that eg
"Enable configs for rockchip-dfi, rga, hantro, etc. This enables
monitoring of DDR load, usage of the hardware codecs, etc"

You should run make savedefconfig and commit the configs from the
generated defconfig so they're in the right place in the defconfig,
rather than just appending them to end like this.
