However I just saw this in Realview.py timer0 = Sp804(int_num0=34, int_num1=34, pio_addr=0x1C110000, clock0='50MHz', clock1='50MHz') so I guess it's more like 50 MHz for this board. Could someone confirm this?

It very much depends on the implementation though, number of connected slaves, P&R, libraries, etc. AHB is usually around 200-300 MHz and AXI >=400MHz in a 65LP process.
