09ca7098e4 hwpm: Disable setting fs_info for hypervisor 
Set the floorsweeping information for IPs only
if the configuration is non Hypervisor. Force
enable IPs are only valid for native-Linux config.
On hypervisor config, a driver is allowed to only
remap addresses owned by the device node.
Thus, ioremap of perfmux addresses is not allowed
in hypervisor configuration. Add check to prevent
force enable IPs and ioremap in hypervisor
configuration.
