On startup (before kernel_main), the global object pi1541 causes the Pi1541 constructor being called, which calls the Drive constructor, which calls Drive::Reset, which calls m_pVIA->InputCA1 with m_pVIA is still uninitialized. Fix this by passing the pVIA object to Drive via its constructor already.
