Linux Kernel abolished include/linux/config.h long time ago.
(around version v2.6.18..v2.6.19)
We don't need to provide Linux copatibility any more.
This commit deletes include/linux/config.h
and fixes source files not to include this.

The purpose of the __raw* IO accessors is to provide
IO access in native-endian order. However in the current
MIPS implementation, the 16 and 32 bit variants of the
__raw accessors are swapping the values on big-endian
systems if the CONFIG_SWAP_IO_SPACE option is enabled.
The patch changes the IO accessor macros to fix this
broken behaviour.

All other IO accessor functions are using the
'inline' directive. Use that also for the __in*s
to make it consistent with the other variants.

We're passing a volatile pointer to a function which is expecting a non-
volatile pointer. That's potentially dangerous, so gcc warns about it.
Confirmed with ELDK 4.2 (GCC 4.2.2) and Sourcey G++ 4.2 (GCC 4.2.3).
To fix this, we add a volatile attribute to the argument in question.
The virt_to_phys function in Linux kernel also does the same thing.

virt_to_phys() returns the physical address given a virtual. In most
cases this will be just the input value as the vast majority of
systems run in a 1:1 mode.
However in systems that are not running this way it should report the
physical address or ~0 if no mapping exists for the given virtual
address.

map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.
This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.

Although mips_io_port_base is currently a part of IDE command, it is quite
fundamental for MIPS I/O port access such as in[bwl] and out[bwl]. So move
it to MIPS general part, and introduce `set_io_port_base()' from Linux.
This patch is triggered by multiple definition of `mips_io_port_base' build
error on gth2 (and tb0229 also needs this fix.)

Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command
is fully finished. The sync() is defined in each CPU's io.h file. For
those CPUs which do not need sync for now, a dummy sync() is defined in
their io.h as well.
