Subject: [PATCH v2 4/4] arm: zynq: Enable arm_global_timer

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

Signed-off-by: Soren Brinkmann <soren.brinkmann@...inx.com>
Acked-by: Daniel Lezcano <daniel.lezcano@...aro.org>

v2:
 - rename DT node: global_timer@... => timer@...
 - add Daniel's ACK
