Hi,

(The motivation is the single-binary project).

This series is preliminary on unifying endianness for the
single binary. The goal is to have a clean API ready for
harder refactor.

First part, we remove the _notdirty() and leul_to_cpu() helpers,
then we prepare the subpage_ops[] MemoryRegionOps to handle
distinct endianness in the same binary, and finally we add
a pair of ldn()/stn() variants to directly infer the access
size and endianness from a MemOp argument.

Second part we let all targets set the
TARGET_USE_LEGACY_NATIVE_ENDIAN_API definition, then restrict
our headers to only expose legacy "native" endian declarations
when this definition exists.
This will allow us to gradually clean the repository,
eventually removing the legacy API.

Please review,

Phil.
