hw/arm/bcm2836: Rename bcm2836 type/struct to bcm283x

Browse Source 
Our BCM2836 type is really a generic one that can be any of
the bcm283x family. Rename it accordingly. We change only
the names which are visible via the header file to the
rest of the QEMU code, leaving private function names
in bcm2836.c as they are.

This is a preliminary to making bcm283x be an abstract
parent class to specific types for the bcm2836 and bcm2837.
