x86/xen: separate PV and HVM hypervisors

Browse Source 
As a preparation to splitting the code we need to untangle it:

x86_hyper_xen -> x86_hyper_xen_hvm and x86_hyper_xen_pv
xen_platform() -> xen_platform_hvm() and xen_platform_pv()
xen_cpu_up_prepare() -> xen_cpu_up_prepare_pv() and xen_cpu_up_prepare_hvm()
xen_cpu_dead() -> xen_cpu_dead_pv() and xen_cpu_dead_pv_hvm()

Add two parameters to xen_cpuhp_setup() to pass proper cpu_up_prepare and
cpu_dead hooks. xen_set_cpu_features() is now PV-only so the redundant
xen_pv_domain() check can be dropped.
