[Om2008.9] power on GPS

[arne anka]

/sys contains usually at least as many links as there are real files, i  
find it rather confusing but there's probably a reason.
simply do

ls -alF

or

file

for both files

ls -alF /sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron
ls -alF  
/sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron

most likely one of it is a link pointing to the other one.
