Eric Lai 5b89bf4666 lib: Introduce fw_config_get_field ...

In some cases, fw_config is used for ids like sar_id, sku_id etc.
To avoid calling fw_config_probe over and over, hence provide the
method to return the value then caller can use the switch case
instead of if else statement.

TEST=get fw_config field value on nivviks.
[INFO ]  fw_config get field name=DB_USB, mask=0x3, shift=0, value =0x1
