Some clocks shouldn't be automatically disabled in clk_disable_unused(),
otherwise kernel hangs. Mark those clocks with:
- CLK_IS_CRITICAL flag, when there won't be any consumers for that
clock, but system can't function when it's gated
- CLK_IGNORE_UNUSED flag, when consumer driver will be probably added
later
That makes it possible to run the kernel without passing the
"clk_ignore_unused" param.Applied, thanks.
