mlxsw: reg: Add Monitoring Port Analyzer Table register

Browse Source 
The MPAT register is used to query and configure the Switch Port Analyzer
(SPAN) table. This register is used to configure a port as a mirror output
port, while after that a mirrored input port can be bound using MPAR
register.
