Iru Cai 7691ebc379 Doc/mb/hp: rename the document about HP laptops with KBC1126 
Later EliteBooks use different EC chips and have different EC firmware
interfaces, so rename the document elitebook_series.md to a more
precise name and also do some rewriting.

A link to the code review page for 8760w is also added because the
port for this laptop is not merged yet.
