Subject: [PATCH v4 08/14] apm32: remove paravirt_enabled() use

There is already a check for apm_info.bios == 0, the
apm_info.bios is set from the boot_params.apm_bios_info.
Both Xen and lguest, which are also the only ones that set
paravirt_enabled to true, never set the apm_bios.info. The

Xen folks are sure force disable to 0 is not needed, we
recently forced disabled this on lguest. With this in place
the paravirt_enabled() check is simply not needed anymore.
