ARM: tegra: apalis-tk1: support v1.2 hardware revision
Support the V1.2 hardware revision with the following pin muxing
changes:
Ddc_scl_pv4 and ddc_sda_pv5 previously used as Apalis GPIO3 and GPIO4
are now used as DDC pins.
Gen2_i2c_scl_pt5 and gen2_i2c_sda_pt6 previously used as DDC pins are
now used as USB power enable signals.
Usb_vbus_en0_pn4 and usb_vbus_en1_pn5 previously used as USB power
enable signals are now used as GPIO3 and GPIO4.
