Add HP ENVY dv6-7000 and dv7-7000 series config

[mbc07]

Created and tested this config on an HP ENVY dv6-7302eo but should work on any ENVY dv6-7xxx and ENVY dv7-7xxx models since those two notebook series uses the same motherboard and shares the same BIOS and EC chip on all models.

The separate config files are identical apart from the NotebookModel string, I duplicated them only to account for the different model string reported by the BIOS between the 15" models (dv6) and the 17" models (dv7)...
