Cleanup the LEDs code to use ioremap()/writeb() to access the register.
This allows us to move the definitions out of a header file directly
into the ebsa285 support code.

Annotate the low level hardware locks which must not be preempted.
In mainline this change documents the low level nature of
the lock - otherwise there's no functional difference. Lockdep
and Sparse checking will work as usual.

Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
multi-platform builds. This also removes the requirement for a platform to
have a mach/hardware.h.
The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
Per Arnd Bergmann, other values are likely to be incorrect, but this commit
does not try to address that issue.

Convert pcibios_assign_all_busses from a define to inline so platforms can

Netwinder was using gpio_xxx names which could clash with the GPIO
layer. Add a 'nw_' prefix to ensure that these remain separate.

Avoid unnecessarily pollution of the kernel's namespace by avoiding
mach/hardware.h in mach/io.h. Include this header file where necessary.
