Summary 07389: inferno: Wrong DAC sound
Description Since MAME 0.211 Inferno (Williams) is playing the wrong DAC sound.
Steps To Reproduce The PIA6821 improvements in MAME 0.211 makes the problem. Do i revert the PIA changes the sound in Inferno works again!

See https://git.redump.net/mame/commit/?id=2e0f4af6ee693fb6f40183bc60ef16db826c8780
PIA6821 improvements: Fixed method names in comments. Removed unused set_port_a_z_mask calls and m_port_a_z_mask variable. For port A reads, only use the DDR for reading pins unless. Provide an override option when a device depends on slightly undefined behavior of an external device driving the pins and changing the value read. One board seems to need this (coinmstr). I don't have the schematics, but it seems it uses this to check its meter operation [Mike Harris].
