This reverts commit 03a3bb7ae631 ("hwrng: core - Freeze khwrng
thread during suspend"), ff296293b353 ("random: Support freezable
kthreads in add_hwgenerator_randomness()") and 59b569480dc8 ("random:
Use wait_event_freezable() in add_hwgenerator_randomness()").

These patches introduced regressions and we need more time to
get them ready for mainline.

Add platform support for the new IP found on sam9x60 SoC. For this
version, if the peripheral clk is above 100MHz, the HALFR bit must be
set. This bit is available only if the IP can generate a random number
every 168 cycles (instead of 84).

When runtime-pm is disabled, we get a few harmless warnings:

drivers/char/hw_random/omap3-rom-rng.c:65:12: error: unused function 'omap_rom_rng_runtime_suspend' [-Werror,-Wunused-function]
drivers/char/hw_random/omap3-rom-rng.c:81:12: error: unused function 'omap_rom_rng_runtime_resume' [-Werror,-Wunused-function]

Mark these functions as __maybe_unused so gcc can drop them
silently.
