kmp204x: introduce QRIO GPIO functions
The QRIO GPIO functions can be of general interest. They are thus added
to a qrio.c and their prototype are available from kmp204x.h. The QRIO
prst function are also included in this file, as well as the functions
required for the I2C deblocking support (open-drain).
