hwrng: rockchip - add hwrng driver for Rockchip RK3568 SoC
Rockchip SoCs used to have a random number generator as part of their
crypto device, and support for it has to be added to the corresponding
driver. However newer Rockchip SoCs like the RK3568 have an independent
True Random Number Generator device. This patch adds a driver for it,
greatly inspired from the downstream driver.
The TRNG device does not seem to have a signal conditionner and the FIPS
140-2 test returns a lot of failures. They can be reduced by increasing
RK_RNG_SAMPLE_CNT, in a tradeoff between quality and speed. This value
has been adjusted to get ~90% of successes and the quality value has
been set accordingly.
