Use ARRAY_SIZE instead of having similar implementation in each drivers.

Hi Jagan Teki,
This is v2 per your request.
v2:
Fix checkpatch issues, now checkpatch only shows below warnings:
a few WARNING: Avoid CamelCase
and a WARNING: line over 80 characters
#134: FILE: drivers/net/npe/IxEthDBFeatures.c:150:
+ if
(ixEthDBTrafficClassDefinitions[trafficClassDefinitionIndex][IX_ETH_DB_NPE_A_FUNCTIONALITY_ID_INDEX]
== npeAImageId.functionalityId) {
Obviously, I prefer v1 for below reasons:
1. The diff in v2 becomes bigger and makes it harder for review.
2. The whole file in drivers/net/npe/IxEthDBFeatures.c uses 4 spaces as indent,
only the lines touched by this patch uses tab as indent (to make checkpatch
happy).
This makes the code looks odd after apply v2, I don't think this is an
improvement.
Well, it's up to maintainer to pick up the version he prefer.
Regards,
Axel
