[Qemu-devel] [PULL 36/47] hw/usb: Use the IEC binary prefix definitions

[Paolo Bonzini <pbonzini@redhat.com>]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

It eases code review, unit is explicit.

Patch generated using:

  $ git grep -E '(1024|2048|4096|8192|(<<|>>).?(10|20|30))' hw/ include/hw/

and modified manually.
