fpga: socfpga: Rename 'timeout' variable as 'time_left'

There is a confusing pattern in the kernel to use a variable named
'timeout' to store the result of
wait_for_completion_interruptible_timeout() causing patterns like:

        timeout = wait_for_completion_interruptible_timeout(...)
        if (!timeout) return -ETIMEDOUT;

with all kinds of permutations. Use 'time_left' as a variable to make the
code self explaining.

Fix to the proper variable type 'long' while here.
