You're right, I'll update it.

For most of files changed the benefit here is factoring out a common pattern
using the standard function roundup/down_pow_two() which now provides correct
64bit results.

As for of/device.c and arm64/iort.c it's more of a readability enhancement. I
consider it's easier to understand than the current calculation as it abstracts
the math.
