microblaze: Convert axi timer to DM driver

Browse Source 
Move axi timer driver from Microblaze to generic location.
Origin implementation was irq based with counting down timer.

CONFIG_TIMER drivers are designed differently that timer is free running up
timer with automatic reload without any interrupt.
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).
