Several issue have been reported building the driver on big endian
systems. Following commits were done on driver Kconfig:

d4620396 Staging: brcm80211: disable drivers except for X86 or MIPS platforms
15e5201d Staging: brcm80211: disable drivers for PPC platforms

These problems have been resolved so the added 'depends' lines in
the Kconfig have been removed.

Compile tested it for following architectures:
little endian
	x86
	x86_64
	arm
	mips
big endian
	ppc64
	sparc64
	mips

Building for the ARM resulted in a compiler warning about usage of
a possibly uninitialized variable. The warning is valid and the

Code cleanup. Removed MIPS specific 'sync' instruction since this is not
required for the chips that this driver supports. MIPS specific macro's
were now the same as non-MIPS register access macro's and thus have been
deleted. Also added comment that makes clearer what the benefit of these
macro's is. Unified big and little end register access macro's.
