mb/google/dedede/var/pirika: Add initial fw_config configuration setting

1. Describe the FW_CONFIG probe for the settings for Palutena.
    - WIFI_SAR_ID_0 for AW Wi-Fi module AW-CM421NF
    - WIFI_SAR_ID_1 for Intel Wi-Fi module AX211NGW

2. In contrast to the AW Wi-Fi module, the Intel Wi-Fi module needs
to load a SAR table in dedede platform.

3. For Palutena project, the SKU ID segment of Palutena is set for
"0x350000~0x35FFFF".
