[Qemu-devel] [PATCHv2 03/10] apb: rename APB functions to use sabre prefix

[Mark Cave-Ayland]

As hinted in the comment at the top of the file, the naming convention for the
APB types/QOM functions isn't correct. As a starting point we can at least
rename the APB type and related functions to improve the readability of apb.c.
