The INTERNAL_SIZE_T default is size_t, which already is 64-bit on 64-bit
platforms and 32-bit on 32-bit ones. We can thus drop the #define and go
back to the minimal <asm/types.h>.

sizeof(dma_addr_t) == 8 shouldn't introduce any functional change, because
we can't have DMA on sandbox. For now it suppresses benign warnings about
mismatched pointer and integer sizes when some headers are included.

sizeof(phys_addr_t) == 8 was already the case on systems with
__x86_64__. As CONFIG_64BIT now is set according to the bitness
of the compiler, we can migrate this fully to Kconfig.

Many architectures duplicate the same fixed type definitions
as in <asm-generic/int-ll64.h>.

Include <asm-generic/int-ll64.h> from <asm/types.h>, and remove
the duplicated code.

Note:
Linux commit 0c79a8e29b5f ("asm/types.h: Remove
include/asm-generic/int-l64.h") unified the kernel space
definition into int-ll64.h. Barebox also adopts int-ll64.

This introduces the bitsperlong.h file for the remaining architectures.
It's purpose is to define BITS_PER_LONG which in the next step can be used
by a generic posix_types.h file.

Instead of letting all architectures define their own dma_addr_t use
a common place in include/linux/types.h and use a Kconfig symbol that
architectures can select to define the width of dma_addr_t. The same
is done in the Kernel.

On x86_64 we need CONFIG_PHYS_ADDR_T_64BIT to make the resource sizes
64bit. The kernel has this as a Kconfig variable, but on barebox sandbox
will build with whatever compiler we find, so we can't put it into Kconfig.

Move platform independent header files to arch/sandbox/include/asm, leaving
those in asm/arch*.
