Subject: [PATCH 04/12] firmware: stratix10-svc: increase msg arg size

From: Ang Tien Sung <tien.sung.ang@...el.com>

Increase args array from 3 to 6, which is used for args to be passed
via registers and not physically mapped buffer. This is to cater
for the new SDM crypto commands that requires the extra arguments
to contain the physical address of shared buffers.
