chryangl gets in game but gets stuck when betting or after some time in attract mode; chryangla shows a black screen but can enter various test screens. I'm decently confident these aren't decryption issues but maybe extra protection

(nw) Regressions from this commit are quite easily possible. Prioritization, acknowledgment and vectoring of the various interrupt sources are largely functions of ASICs which seem to be incompletely documented in Japanese, let alone English.
* 6821pia: fix method names in comments
* zwackery: Remove PIA port A z_mask setting.
This would only be relevant if the PIA was read while in output mode.
These are inputs, and only read in input mode, so z_mask is not relevant.
* thomson: move pia pullup resistors from z_mask to read handler.
* 6821pia: remove unused set_port_a_z_mask calls.
* dgn_beta: move pia pullup resistors from z_mask to read handler.
* mpu3: Don't invert the VFD power on reset line.
It doesn't go through an inverter. I believe this was done to work
around a bug in the PIA port A implementation.
* pia6821: remove m_port_a_z_mask variable.
* 6821pia: 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.
