Subject: [PATCH v2] 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.

Changes in v2:
- Drop explicit Rockchip Hantro enablement, as this should already be
  autoselected as the Kconfig option's default if Hantro is enabled.
- Also enable PM_DEVFREQ_EVENT, which is a prerequisite to rockchip-dfi.
- Order the defconfig options at the correct locations, as per
  `savedefconfig`.
- Link to v1: https://lore.kernel.org/r/20250626-rk3588-defconfig-v1-1-39a19a41c181@collabora.com
