pinctrl: samsung: add exynosautov920 pinctrl

Add pinctrl data for ExynosAutov920 SoC.
It has a newly applied pinctrl register layer for ExynosAuto series.

Pinctrl data for ExynosAutoV920 SoC.
 - GPA0,GPA1 (10): External wake up interrupt
 - GPQ0 (2): SPMI (PMIC I/F)
 - GPB0,GPB1,GPB2,GPB3,GPB4,GPB5,GPB6 (47): I2S Audio
 - GPH0,GPH1,GPH2,GPH3,GPH4,GPH5,GPH6,GPH8 (49): PCIE, UFS, Ethernet
 - GPG0,GPG1,GPG2,GPG3,GPG4,GPG5 (29): General purpose
 - GPP0,GPP1,GPP2,GPP3,GPP4,GPP5,GPP6,GPP7,GPP8,GPP9,GPP10 (77): USI
