mb/asus/p8x7x-series: Add Z77-A as a variant

Constructed from a mix of similar boards, boardview and vendor firmware
analysis. Not hardware tested.

It has a RTL8111F LAN chip with no EEPROM for vital product data like
LED configurations or MAC addresses. User will need to set their MAC
address during 'make menuconfig'.
