The RK3576 SoC contains a RKRNG block that can be used to generate
random numbers using the rockchip_rng driver.

Add compatible for RK3576 to support random numbers:

  => rng list
  RNG #0 - rng@2a410000

  => rng
  00000000: 36 dd ab 98 ec fb fe d1 cf 36 b3 e1 9b 3d 00 90  6........6...=..

Add support for rkrng variant, used by e.g. RK3528 and RK3576.

Imported from vendor U-Boot linux-6.1-stan-rkr5 tag with minor
adjustments for mainline.

Linux commit 6ee0b9ad3995 ("arm64: dts: rockchip: Add rng node to
RK3588") merged for v6.15-rc1 add a proper rng node to the device tree.
The compatible used differs compared to what U-Boot is currently using.

Replace the old trngv1 compatible with the dts/upstream compatible in
the rng driver and remove the old rng node compatible override from SoC
u-boot.dtsi to keep rng working after the driver change.

Linux commit afeccc408496 ("arm64: dts: rockchip: add DT entry for RNG
to RK356x") merged for v6.12-rc1 add a proper rng node to the SoC DT.
The compatible used differs compared to what U-Boot is currently using.

Add support for the rk3568-rng used in upstream Linux. Support for the
cryptov2-rng compatible is still kept because PX30/RK3326 and RK3308 are
still using it.

The different macros use writel which is defined in asm/io.h, so let's
include the header so users of hardware.h do not need to include
asm/io.h as well.

While at it, remove asm/io.h includes wherever
asm/arch-rockchip/hardware.h is included already.

Usage of common.h is deprecated.

* Remove common.h from RNG drivers.
* Sort includes.
* Add time.h to sandbox driver.
* Add linux/types.h to rng.h to provide size_t.

This adds support for the TRNG found in the RK3588 SoC to the
rockchip_rng driver so that it can be used for things such as
seeding randomness to Linux.

Changes in V3:
 - Moved notes from commit to cover letter.
 - Added Reviewed-By tag.

Changes in V2:
 - Modified Kconfig to note that the Rockchip RNG driver supports all
   versions of the hardware (v1, v2, and the trng in the rk3588).

Try to maintain some consistency between these variables by using _plat as
a suffix for them.

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.
