GTA04 has a W2SG0004 module connected to UART2 of the OMAP3
processor. A GPIO can pulse the on/off toggle switch.

Note that there is no WAKEUP output from the W2SG0004,
hence we can't use the generic SirfStar binding.

The VSIM regulator is used to power on/off the LNA of an
external active GPS antenna so that a driver can turn the
LNA off if GPS is not needed to save battery energy.
This reads as if you did low->high->low to turn GPS on, then
low->high->low to turn GPS off again. Is that correct?
