[asmc] Add support for MacBook Pro 11,2

This patch will add support for MacBookPro 11.2.
For the macros, the MBP11_* macros (for the existing MacBookPro11.3) did not
match so they have been renamed to MBP113_* and a new MBP112_* has been
added (modified copy of MBP11_*).

Some trailing whitespaces may have been removed automatically.
