MLK-14675: ARM: dts: set pll4 rate for audio There is noise when use ssi master mode. the reason is the ssi rate is not accurate for ssi master mode, show below. pll3_pfd2_508m 0 0 508235294 0 0 ssi3_sel 0 0 508235294 0 0 ssi3_pred 0 0 127058824 0 0 ssi3_podf 0 0 63529412 0 0 ssi3 0 0 63529412 0 0 ssi2_sel 0 0 508235294 0 0 ssi2_pred 0 0 127058824 0 0 ssi2_podf 0 0 63529412 0 0 ssi2 0 0 63529412 0 0 so we need to switch ssi's parent to pll4 (which is dedicate audio pll), and set a proper rate for pll4, we select 786432000Hz, which can generate 32kHz,48kHz,96KHz.
