lib: Perform early initialization of FW config in ramstage

This patch moves the fw_config_init() function from `BS_DEV_INIT_CHIPS`
boot state to its prior state aka `BS_PRE_DEVICE`.

Without this patch the early ramstage code (running from BS_PRE_DEVICE
boot state) is unable to probe PCI devices using FW_CONFIG.

For example: below sample code is unable to give the correct state of
the UFS PCI device with FW_CONFIG `STORAGE_UFS = 0` at early ramstage
function:

device ref ufs on
    probe STORAGE STORAGE_UFS
  end

Without this patch: The results is UFS device is enable

With this patch: The results is UFS device is disable
