This adds support for Chips & Technologies 82C606 CHIPSpak Multifunction
Controller emulation. It is similar enough to 82C710 that supporting the
82C606 is merely a matter of adding a variant to the existing code.
The 82C606 is notably used in the Victor V86P portable computer.
Compared to 82C710, the 82C606 provides neither floppy nor IDE hard
driver support. On the other hand it provides a RTC with non-volatile
CMOS RAM and a Game Port. The base addresses and interrupt lines of the
peripherals are configurable.
The 82C606 SuperIO allows reconfiguring the interrupt line used for the
UART alarm at runtime, including disabling it altogether.
While at that, correct the type in the serial_setup() prototype to be
the same as serial_t.irq uses.
Overhauled the read portion of the PIX TRANS command (fixes white corruption in some instances while keeping everything already working fine).
Fixed Miro 10SD recalctimings issue about losing graphics mode.
DWORD mode SVGA CRTC bit fixed when S3 DWORD mode bit is enabled.
Reworked the pix tranfer register to allow a word in a byte transfer.
Added an alternative bios selection for the SPEA Mirage 801 card (3.05I and 4.01, the latter being the default now.
Added the MiroCrystal 10SD 805 VLB, Phoenix 801 ISA, MiroVideo 40SV 968 VLB/PCI, SPEA Mercury P64V 968 PCI , SPEA Mirage P64 Trio64 VLB cards.
Removed some non-working S3 cards like the Trio64V+ VLB and Elsa Winner 2000 Pro X VLB (only PCI variants of these cards are now in)
- A global variable added as vm_name
- This variable can be filled with the `--vmname "Name"` or `-V "Name"` parameter.
- If there are no such a parameter definied this variable will filled up with the directory name.
- The Discord module displays this global variable, as VM name.
- Various 86Box managers can use this feature to display fancy VM names, instead of GUID folder names.
- This variable can be easily used later for adding cool things, like the VM name in title bar, etc.
