pinctrl: mediatek: add rsel setting on mt8192

1. I2C pins's resistance value can be controlled by rsel register.
This patch provides rsel (resistance selection) setting on mt8192.
2. Also add the missing pull type array for mt8192 to document the
pull type of each pin and prevent invalid pull type settings.
