[PATCH 1/2] dt-bindings: clock: add description of 74aup1g157gw

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

74aup1g157gw needs i0 and i1 pin as input, select and output it by
sel gpio pin. This patch adds description for 74aup1g157gw as clock
multiplexer.
"nxp,74aup1g157gw-clk" will select most closest input as output,
"nxp,74aup1g157gw-audio-clk" will select 48kHz/44.1kHz categorized
input as output.
