Since commit 2fad972d45c4 ("ARM: dts: Add mclk entry for Peach boards"),
sound card detection is broken on peach boards and gives below errors:
[ 3.630457] max98090 7-0010: MAX98091 REVID=0x51
[ 3.634233] max98090 7-0010: use default 2.8v micbias
[ 3.640985] snow-audio sound: HiFi <-> 3830000.i2s mapping ok
[ 3.645307] max98090 7-0010: Invalid master clock frequency
[ 3.650824] snow-audio sound: ASoC: Peach-Pi-I2S-MAX98091 late_probe() failed: -22
[ 3.658914] snow-audio sound: snd_soc_register_card failed (-22)
[ 3.664366] snow-audio: probe of sound failed with error -22
This patch adds missing assigned-clocks and assigned-clock-parents for
pmu_system_controller node which is used as "mclk" for audio codec.
