[ 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.
