fsl_usdpaa: Protect against truncation
is_power_of_2 is a Linux function that takes unsigned long. it was
used by our new function is_power_of_4 which takes u64. Trucation
is possible because unsigned long is 32 bits wide in 32 bit
applications. This patch removes the dependancy on is_power_of_2 to
solve this issue
