Tell L1CTL_FBSB_REQ the expected received signal level

As Dieter points out, this drastically improves the resiliance to high
receive levels on the C155.  We cannot blindly assume a received signal
level of -85 dBm if the BTS is 2m away and we actually receive -40 dBm.

This patch extends the L1CTL_FBSB_REQ data structure in layer 1 with the
respective field, as well as the l1ctl_tx_fbsb_req() API function called
from the various layer23 apps.

"mobile" and "bcch_scan" already did a PM request and thus know the
expected signal power.  "ccch_scan" and "cbch_sniff" apparently don't
do, so the -85 dBm constant is now hardcoded into the host-side source
code there, and should probably be fixed in a follow-up patch.
