ARM: dts: ux500: Convert HREF audio to audio-graph-card2

Describe the HREF500 and HREF520 sound hardware with two-link audio
graph cards in their PMIC-specific HREF DTSIs, and name the card
HREF-500. Connect MSP1 to codec DAI 0 for playback and MSP3 to codec
DAI 1 for capture.

Describe the DSP_A format, codec-provided bit and frame clocks,
16-by-16-bit TDM frame and active slots on the graph endpoints. Keep the
clocks running continuously, matching the legacy machine driver's normal
one- and two-channel mode.

Keep each complete card, including its endpoint graph, connector
widgets and routes, in the existing PMIC-specific HREF DTSI. The AB8500
variant exposes six digital microphone endpoints. AB8505 has neither
the digital microphone interface nor its VDMIC regulator, so leave
these endpoints out of HREF520 and remove its stale regulator and pin
configuration nodes.

Select ULPCLK as the fixed parent of the codec audio clock in the
HREF-specific codec DTSIs. This replaces the machine driver clock
control with declarative board policy.
