mainboard/hp: Add initial support for Pavilion m6-1035dx

This was a pathetically easy port, where all the components are
already supported. This is basically a verbatim copy of amd/parmer.
The EC is an ENE KB932, which is a part that does surprisingly little
for an EC. This also means we need almost no code to get it working.
I've "select"ed the EC in Kconfig, which is the only difference from
parmer, although the keyboard worked fine without it.

I haven't coupled in the ACPI code from the EC yet, so battery level
is not readable from the OS. Hotkeys work except for brightness
control, and the CapsLock LED blinks at regular intervals instead of
following the CapsLock key.
