d457de0fe0 event/octeontx2: add devargs to modify chunk slots
Add devargs support to modify number of chunk slots. Chunks are used to
store event timers, a chunk can be visualised as an array where the last
element points to the next chunk and rest of them are used to store
events. TIM traverses the list of chunks and enqueues the event timers
to SSO.
If no argument is passed then a default value of 255 is taken.

Example:
	--dev "0002:0e:00.0,tim_chnk_slots=511"

464060c02f event/octeontx2: add devargs to disable NPA
If the chunks are allocated from NPA then TIM can automatically free
them when traversing the list of chunks.
Add devargs to disable NPA and use software mempool to manage chunks.

Example:
	--dev "0002:0e:00.0,tim_disable_npa=1"
