Looking to your first log [1], it seems that CNTFRQ is not set correctly:

Generic Timer IRQ: phys=30 hyp=26 virt=27 Freq: 0 KHz

The CNTFRQ register should be set by the firmware/bootloader. Does the 
Linux kernel is booting on baremetal with the same firmware/bootloader?
If yes, do you use the same device tree?
