hw/rtc/pl031: : Remove PL031State::migrate_tick_offset field

Browse Source 
The PL031State::migrate_tick_offset boolean was only set in
the hw_compat_4_0[] array, via the 'migrate-tick-offset=false'
property.  We removed all machines using that array, lets remove
that property, along with the pl031_properties[] array which is
now empty.
