soc: mediatek: mtk-cmdq: Add cmdq_pkt_acquire_event() function
Add cmdq_pkt_acquire_event() function to support CMDQ user making
an instruction for acquiring event.
CMDQ users can use cmdq_pkt_acquire_event() as `mutex_lock`
and cmdq_pkt_clear_event() as `mutex_unlock` to protect the global
resource modified instructions between them.
cmdq_pkt_acquire_event() would wait for event to be cleared.
After event is cleared by cmdq_pkt_clear_event() in other GCE threads,
cmdq_pkt_acquire_event() would set event and keep executing next
instruction. So the mutex would work like this:
cmdq_pkt_acquire_event() /* mutex lock */
/* critical secton instructions that modified global resource */
cmdq_pkt_clear_event() /* mutex unlock */
Prevent the critical section instructions from being affected by other
GCE threads.

soc: mediatek: mtk-cmdq: Add cmdq_pkt_poll_addr() function
Add cmdq_pkt_poll_addr function to support CMDQ user making
an instruction for polling a specific address of hardware rigster
to check the value with or without mask.
POLL is a legacy operation in GCE, so it does not support SPR and
CMDQ_CODE_LOGIC. To support polling the register address which doesn't
have the subsys id, CMDQ users need to make an instruction with GPR and
CMDQ_CODE_MASK operation to move the register address to be poll into GPR.
Then users can make an POLL instruction with GPR to poll the register
address assigned in previous instruction.

soc: mediatek: cmdq: Refine cmdq_pkt_create() and cmdq_pkt_destroy()
cmdq_pkt_create() and cmdq_pkt_destroy() is not suitable for
client drivers so each client driver has implement its own
function. This refinement would pass struct cmdq_pkt pointer into
cmdq_pkt_create(). In addition, client driver has the struct
cmdq_client information, so it's not necessary to store this
information in struct cmdq_pkt. After this refinement, client
drivers could use these helper funciton instead of implementing
its own version.
