hwrng: ingenic: simplify the code

[Martin Kaiser]

Simplify the ingenic-trng driver a bit. Switch to devm_clk_get_enabled and
devm_hwrng_register. Remove some unused code.

The changes were compile-tested only (I don't have this hardware).

Martin Kaiser (7):
  hwrng: ingenic - enable compile testing
  hwrng: ingenic - remove two unused defines
  hwrng: ingenic - remove dead assignments
  hwrng: ingenic - use devm_clk_get_enabled
  hwrng: ingenic - use dev_err_probe in error paths
  hwrng: ingenic - don't disable the rng in ingenic_trng_remove
  hwrng: ingenic - switch to device managed registration
