helper: hexify correctly handle signed chars

The current implementation of hexify was not correctly handling signed chars.

This function is currently used by the ti-icdi driver and as such was causing
random write issues.

As a note perhaps a better long term fix would be to change to using uint8_t
buffers rather than char. This will require changes to the ti-icdi driver
aswell.
