* Initial implementation of the Yamaha YMF-71x (OPL3-SA2/3) audio controllers
* Give the Intel AN430TX its onboard YMF-715
* Forgotten change to snd_sb_dsp.c
* Disable logging, code cleanup
* Use 32K default SB DSP DMA buffer globally and remove the Yamaha subtype
* Hook up master volume control to the OPL3 as well
* Use custom CD audio filter to apply master volume
* Initial implementation of the OPL3-SA3 bass/treble controls
* Improve CD audio volume filter
* Implement the power management registers
* Move master volume recalc to its own function and update on register write
* Correct YMF-719 PnP ROM filename
* Cleanup
The rework resolves around implementing the clock multiplier and multiplexing rate of the bt485 ramdac alongside existing additional flags for eventual fixes (like cr31 bit 1) as well as the true color bypass (for 16-bit and true color modes). These, together, allow proper rendering of the generic VESA S3 drivers alongside non-VESA ELSA OEM drivers on various guests.
1. Rewritten Sierra SC1502x RAMDAC code to match the manual, allowing proper BPP selection on cards which use it.
2. Added a reference clock variable for cards which have a different default one (ELSA cards namely) on the ICD2061 code.
3. Reorganized RAMDAC selection in the S3 code.
4. Added more ELSA Winner cards based on the 928 chip (ELSA Winner 2000 ISA, 1000 VLB and 1000 PCI based on 928PCI).
5. The horizontal override is now also enabled for ELSA Winner 1000 (928 VLB and PCI) cards with 32bpp set, to avoid wrong horizontal displays.
6. LFB in PCI mode doesn't have the same limitations as on VLB or ISA.
7. Added more hdisp adjustments for the Elsa cards.
8. Mono patterns are now more correct in ROPBLT acceleration (command 14), fixes blackness in some instances of Win95 (matching the 968 manual).
9. Minor cleanup on the accel registers.
