[PATCH 06/12] common/cnxk: fix mbox structs to avoid unaligned access

[Nithin Dabilpuram]

Fix mbox structs to avoid unaligned access as mbox memory
is from BAR space.

Fixes: 503b82de2cbf ("common/cnxk: add mbox request and response definitions")
Fixes: e746aec161cc ("common/cnxk: fix SQ flush sequence")
