mb/google/zork: Switch to using FW_CONFIG instead of SKU_ID 

Currently sku_id is used to enable/disable eMMC as boot media on
Dalboz. This patch will check eMMC bit in firmware configuration
table to enable/disable eMMC.
On Dalboz Proto and EVT devices with eMMC, there was an issue found
after SMT. This patch checks for board_version instead of SKU_ID to
configure eMMC in HS200.
Configure HDMI based on daughterboard_id in FW_CONFIG.

BRANCH=none
BUG=b:152817444
TEST=Check eMMC is enabled or disabled based on the eMMC bit in
     FW_CONFIG.
