The way that the current readX/writeX macros are implemented on sandbox
means that when IO_TRACE is not enabled some code will throw up
incorrect warnings due to how sandbox_{read,write} is implemented. We
instead need to do the "uX __v; __v = sandbox..(..v); __v;" trick that
ARM does.

There are some drivers which call a "dmb" for a type of sync. Add that
as well to sandbox.

This adds more common functions found on other architectures that will
allow for more compile-testing of drivers. These are either dummy
functions as we do not need them or mappings to existing functions,
similar to how other architectures handle it.

In order to compile more drivers, add an empty sync() function.

In include/linux/io.h the declarations of ioread64 and iowrite64
which make use of readq/writeq are guarded with CONFIG_64BIT so
guard the sandbox declarations of readq and writeq also with
CONFIG_64BIT.

This should say 'cast' rather than 'case', so fix it.

Sandbox uses an API to map between addresses and pointers. This allows
it to have (emulated) memory at zero and avoid arch-specific addressing
details. It also allows memory-mapped peripherals to work.

As an example, on many machines sandbox maps address 100 to pointer
value 10000000.

However this is not correct for ACPI, if sandbox starts another program
(e.g EFI app) and passes it the tables. That app has no knowledge of
sandbox's address mapping. So to make this work we want to store
10000000 as the value in the table.

Add two new 'nomap' functions which clearly make this exeption to how
sandbox works.

This should allow EFI apps to access ACPI tables with sandbox, e.g. for
testing purposes.

Remove and replace common.h and config.h in sandbox when it's not needed
and add some explicit includes where needed.

Generic version of io.h should be included at the end of
architecture-specific ones to make sure that arch implementations are
used and to avoid redefinitions.
