    - added reset callback to do reset and skip the standard procedure
    - added limited_regs flag to avoid to touch unexpected registers
    - Fixes for AD1981A and added a special patch for an intel motherboard
  - sequencer
    - check the possible infinite loop in priority queues
    - reset the timer at continue if not initialized yet
  - changed synchronize_irq() for new api with an argument
  - NM256 driver - fixes the lock up on NM256 ZX
  - VIA8233 - implementation of SG buffer
