ARM: dts: apq8084: add pinctrl for primary and quaternary MI2S 



APQ8084 has 4 MI2S ports which can be used for connecting
different device like external Modem and Audio codec. Each
of these MI2S ports have one MCLK line and atleast 4 other
line with SCLK, WS and 2 DATA lines. Set pinctrl for all
GPIOs which can be used for Primary and Quaternary MI2S ports.
