zynq: Convert arm twd timer to DM driver

Browse Source 
Move arm twd timer driver from zynq to generic location.

DM timer drivers are designed differently to original driver. Timer is
counting up and not down.
Information about clock rates are find out in timer_pre_probe() that's
why there is no need to get any additional information from DT in the
driver itself (only register offset).
