ARM: tegra: apalis_t30: pinmux clean-up

Clean-up pinmuxing:
- white-space clean-up
- explicitly disable input of BKL1_ON, BKL1_PWM and BKL1_PWM_EN#
- annotate Apalis I2C3 usage for CAM
- get rid of nvidia,lock property
- add missing eMMC sdmmc4_cmd_pt7 and explicitly enable input
- explicitly disable lcd_dc1_pd2 (e.g. LM95245 I2C address pin)
- annotate TOUCH_PEN_INT# being on-module
- As underscores in node names are not recommended replace them all
  where possible with dashes.
