From: Robert Marko <robimarko@gmail.com> [ Upstream commit 86e78995c93ee182433f965babfccd48417d4dcf ] While fixing up the driver I noticed that my IPQ8074 board was hanging after CPUFreq switched the frequency during boot, WDT would eventually reset it. So mark apcs_alias0_core_clk as critical since its the clock feeding the CPU cluster and must never be disabled.
