Andy Shevchenko 5b3b3e35ac Documentation: gpio: Input mode is not true Hi-Z
The true Hi-Z (a.k.a. high impedance) mode is when pin is completely
disconnected from the chip. This includes input buffer as well.
Nevertheless, some hardware may not support that mode and they are
considering input only as Hi-Z, but more precisely it is an equivalent
to that, in electronics it's basically "an antenna mode".

Sligthly correct documentation to take the above into consideration.
