Lots of platforms contain clocks which if turned off would prove fatal. The only way to recover is to restart the board(s). This driver takes references to clocks which are required to be always-on. The common clk framework will then take references to them. This way they will not be turned off during the clk_disabled_unused() procedure. In this patch we are identifying clocks, which if gated would render the STiH410 development board unserviceable.
