msm: eva: Add Lanai EVA HFI check

Browse Source 
Adds XRA, DLFL, DLFD, RGE and ITOF packets sanity check.
Optimizes packet type table to avoid linear search during
each packet handling. Instead use packet type as index to expedite
searching. Packet type table grows to over 60 entries and each
entry uses 40B. There will be quite some memory access delay for
each packet handling without optimization.
