octeontx2-af: return VWQE timer delay in NIX HW info

Browse Source 
Update the NIX_GET_HW_INFO mailbox message to return the VWQE timer
delay, which is used for vector packet wait time calculation.
Repurpose the existing rsvs16 reserved field in struct nix_hw_info
to vwqe_delay and populate it by reading the NIX_AF_VWQE_TIMER
register (applicable for non-OTX2 silicon).
