Simon Glass b71bea7129 gpio: Report errors when GPIOs cannot be read 
Some controllers do not allow the output value to be read. Detect this and
report the error in that case.

Simon Glass 4c80c53c00 gpio: Correct handling of 'gpio status' 
This is broken - we need to look at the first two characters to distinguish
'gpio status' from 'gpio set'.

Fixes: 0ffe6ab5 (gpio: Allow 's' as an abbreviation for 'status')

Simon Glass 2e192b245e Remove the cmd_ prefix from command files 
Now that they are in their own directory, we can remove this prefix.
This makes it easier to find a file since the prefix does not get in the
way.
