[Qemu-devel] [PATCH] Add missing initial values for PIIX3 function 0 (PIRQRC)

[Sebastian Herbszt]

According to the 82371SB (PIIX3) specification (290550-002)
2.2.10. PIRQRC[A:D]-PIRQx ROUTE CONTROL REGISTERS (Function 0)
all four registers (60h - 63h) should have the initial value of 80h.
Add the missing initial value for registers 61h - 63h.
