pinctrl: rockchip: Make the gpio base started from 1000
If the gpio base is started from 1000, the "gpio = 0" will
be invalid, that can avoid something unforeseen. The real
pin number is "gpio number - 1000".
If you cat the gpio log, you will see the log like this:
rk3399:/ # cat d/gpio
GPIOs 1000-1031, platform/pinctrl, gpio0:
gpio-1004 ( |bt_default_wake_host) in lo
gpio-1005 ( |power ) in hi
gpio-1009 ( |bt_default_reset ) out lo
gpio-1010 ( |reset ) out lo
gpio-1011 ( |? ) out hi
GPIOs 1032-1063, platform/pinctrl, gpio1:
gpio-1034 ( |int-n ) in hi
gpio-1035 ( |vbus-5v ) out lo
gpio-1036 ( |vbus-5v ) out lo
gpio-1045 ( |enable ) out hi
gpio-1046 ( |vsel ) out lo
gpio-1049 ( |vsel ) out lo
gpio-1056 ( |int-n ) in hi
GPIOs 1064-1095, platform/pinctrl, gpio2:
gpio-1083 ( |bt_default_rts ) in hi
gpio-1090 ( |bt_default_wake ) in hi
GPIOs 1096-1127, platform/pinctrl, gpio3:
gpio-1111 ( |mdio-reset ) out hi
GPIOs 1128-1159, platform/pinctrl, gpio4:
gpio-1150 ( |? ) out hi
gpio-1153 ( |vcc5v0_host ) out hi
gpio-1156 ( |hp det ) in hi
