Pavel Herrmann f5b82c0f9c change all versions of input_data() and output_data() to global weak aliases
This changes input_data() and friends from static function to global symbols
under weak alias, to enable board specific overrides (and therefore get rid of
board-specific code in cmd_ide.c)
Also declare ide_bus_offset in the header file, so other files can use
ATA_CURR_BASE as well.
