Sas address conversion and comparation is widely used in libsas and
drivers. However they are all opencoded and to avoid the line spill over
80 columns, are mostly split into multi-lines.
To make the code easier to read, introduce some helpers with clearer
semantics and replace the opencoded segments with them.
v1->v2:
First factor out sas_find_attached_phy() and replace LLDDs's code
with it.
Remove three too simple helpers.
Rename the helpers with 'sas_' prefix.

Hi Jack,
Thank you very much for the review.

The initial purpose to introduce these helpers is to stop cutting
compare expressions into two lines and to make the code looks clean. We
add more loc in the end because of function declaration and more blank
lines between them.
Thanks,

These 4 look good to me.

These helpers are too simple to replace, we add more loc in the end.
