There are many platforms with exact same value for VM_DATA_DEFAULT_FLAGS
This creates a default value for VM_DATA_DEFAULT_FLAGS in line with the
existing VM_STACK_DEFAULT_FLAGS. While here, also define some more
macros with standard VMA access flag combinations that are used
frequently across many platforms. Apart from simplification, this
reduces code duplication as well.

Stop providing our own arch alloc/free hooks and just expose the segment
offset and use the generic dma-direct allocator.

When compiling with 'W=1' warnings such as the following occur all over
the place:
./include/linux/pfn.h:21:22: warning: comparison of unsigned expression
>= 0 is always true [-Wtype-limits]
which is due to ARCH_PFN_OFFSET being 0 by default
(if CONFIG_NIOS2_MEM_BASE is not changed in the Kconfig). Fix these
warnings by making pfn_valid a static inline function.

Some C-only definition from nios2 asm/page.h are exposed to assembly code.
Extend the !__ASSEMBLY__ section to prevent this.

To align with other architectures, the expression produced by expanding
the macro page_to_virt() should be of type void*, since it returns a
virtual address. Fix that, and also fix up an instance where page_to_virt
was expected to return 'unsigned long', and drop another instance that was
entirely unused (page_to_bus)

shm_align_mask is not defined/used on nios2, thus there is no need to
declare it.
