> On some systems, we come out of the bootloader with some
> gates set with the clock "enabled" but the reset also
> Since 8a53fc511c5e "clk: aspeed: Prevent reset if clock is enabled"
> we check that enabled bit in aspeed_clk_enabled(), and do
> nothing if already set.
> This breaks when the above scenario occurs, as the clock
> is enabled, but the reset still needs to be lifted.
> This patch fixes it by also checking the reset bit (if any)
> and treating a gate in "reset" as being disabled.
