Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

Enable HS-USB device  for the Porter board, defining the GPIO that the
driver should check  when probing (which is the ID output from MAX3355
OTG chip).

Note that there  will be pinctrl-related error messages if both internal
PCI  and  HS-USB drivers are enabled but they should be just ignored.

This patch is  analogous  to the commit 6f4f7156 ("ARM: shmobile:
henninger: enable HS-USB") as there  are no differences between the
boards in this respect.
