Subject: [PATCH] common/cnxk: fix DPI mailbox structure
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit b03c474188383c3d3d529b1c9ca86767e5fb6167 ]

In the existing DPI mailbox structure, one of the fields
spans a 64-bit boundary, making it appear unusual and
complicatng extraction using bit operations.

Patch enlarges csize fields to ensure that mailbox fields
are correctly positioned.

Fixes: b6e395692b6d ("common/cnxk: add DPI DMA support")
