timer: xilinx-timer: use timer_conv_64() to fix timer wrap around

Current xilinx_timer_get_count() implementation does not take into account
the periodic 32-bit wrap arounds, as it directly returns the 32-bit counter
register value. The roll-overs cause problems in the upper timer layers, as
generic timer code expects an incrementing 64-bit value from get_count() to
work correctly.

Add the missing 64-bit up-conversion to fix random hangs/delays in
__udelay().
