Zynq is based on an ARM Cortex-A9 MPCore, which features the arm_global_timer in its SCU. Therefore enable the timer for Zynq.

Nit: node names and property names use '-' not '_'. Plus the generic
names principle suggests the node should be names 'timer' not
'global_timer'. The following would be fine:
global_timer: timer at f8f00200 {
(There's a distinction between node names and labels. '_' is fine in
labels since it doesn't get output into the compiled .dtb.
