Observed the following oops while stress-testing, using multiple

This patch prepares for the incoming patch which swaps the order of
KOBJ_ADD/REMOVE uevent and dt's updating.
The dt updating should come after lmb operations, and before
__remove_memory()/__add_memory(). Accordingly, grouping all lmb operations
before the memblock's.

There are two __packed attributes in qman.h that are both unnecessary
and causing compiler warnings because they're conflicting with
explicit alignment requirements set on members within the structure.
This patch removes them both.

H_SVM_PAGE_IN hcall takes a flag parameter. This parameter specifies the
way in which a page will be treated. H_PAGE_IN_NONSHARED indicates
that the page will be shared with the Secure VM, and H_PAGE_IN_SHARED
indicates that the page will not be shared but its contents will
be copied.
