Add cmdq_pkt_logic_command to support match operation.
cmdq_pkt_logic_command can append logic command to the CMDQ packet,
ask GCE to execute a arithematic calculate instruction,
such as add, subtract, multiply, AND, OR and NOT, etc.
Note that all instructions just accept unsigned calculate.

Add cmdq_pkt_finalize_loop to CMDQ driver.
cmdq_pkt_finalize_loop appends end of command(EOC) instruction and
jump to start of command buffer instruction to make the command

GCE has specific purpose registers, abbreviated as SPR.
Client can us SPR to store data or programs.
In CMDQ driver, it allows client to STORE or LOAD data into SPR.
The value stored in SPR will be cleared after reset GCE HW thread.
There are 4 SPR (register index 0 - 3) in every GCE HW thread.

Use size_mul() to saturate the value, and have memdup_user() fail.
