arm64: defconfig: enable further Rockchip platform drivers

Enable the rockchip-dfi driver as a module, which is used on RK3588 as
well as RK3568 and RK3399 to measure memory bandwidth. For this, we also
enable PM_DEVFREQ_EVENT, which is a requirement for this driver.

Also enable the rockchip-rga driver as a module, which is used on
various Rockchip SoCs, including RK3588 and RK3399, to provide 2d
accelerated image transformations through a V4L2 interface.
