In order to allow separation of data from text, add another layout,
called data_layout. For architectures requesting separation of text
and data, only text will go in core_layout and data will go in
data_layout.
For architectures which keep text and data together, make data_layout
an alias of core_layout, that way data_layout can be used for all
data manipulations, regardless of whether data is in core_layout or
data_layout.

debug_align() was added by commit 84e1c6bb38 ("x86: Add RO/NX
protection for loadable kernel modules")
At that time the config item was CONFIG_DEBUG_SET_MODULE_RONX.
But nowadays it has changed to CONFIG_STRICT_MODULE_RWX and
debug_align() is confusing because it has nothing to do with
DEBUG.
Rename it strict_align()
