clk: ti: dra7: disable the RNG and TIMER12 clkctrl clocks on HS devices
RNG and TIMER12 are reserved for secure side usage only on HS devices, so disable their clkctrl clocks on HS SoCs also. Signed-off-by: Tero Kristo <t-kristo@ti.com> Tested-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
