Add several missing RDMSRs for IDE and USB are missing to avoid the
agressive modification of the high 32 bits of the MSR.

Without this patch some usb devices may fail after printing "reset ehci
host ....." when reading the partition information.

Lemote Loongson 2F family machines use CS5536 as their south bridge and need
these lowlevel interfaces to access the devices on CS5536.

Virtualize the legacy devices on CS5536 as PCI devices.  This way users can
access the CS5536 PCI config space directly as a normal multi-function
PCI 2.2 device.
