lib: utils: Constantify mpxy_rpmi_mbox_data in mpxy_rpmi_mbox

Browse Source 
The mpxy_rpmi_mbox_data is provided by RPMI service group specific
MPXY driver to the common MPXY RPMI mailbox client implementation
so let's constantify mpxy_rpmi_mbox_data in mpxy_rpmi_mbox so that
it is not accidently modified.
