[ Upstream commit 3978f54817559b28535c58a00d3d31bbd5d0b65a ]

Existing amd-sfh driver is programming the MP2 firmware period field in
units of jiffies, but the MP2 firmware expects in milliseconds unit.

Changing it to milliseconds.

Fixes: 4b2c53d93a4b ("SFH:Transport Driver to add support of AMD Sensor Fusion Hub (SFH)")
