[Qemu-devel] [PATCH for-2.13] spapr: drop useless dynamic sysbus device sanity check

[Greg Kurz]

Since commit 7da79a167aa11, the machine class init function registers
dynamic sysbus device types it supports. Passing an unsupported device
type on the command line causes QEMU to exit with an error message
just after machine init.

It is hence not needed to do the same sanity check at machine reset.
