bandaid Dynamic Turbo A operation with old hal's: HAL_MODE_108A

Browse Source 
does not have a rate table in older hal's so if we scan such a
channel the driver will hit an assertion or crash; for old hal's
fallback to using the static turbo rate table for this mode
(not correct but good enough for now given none of the rate
control algorithms understand how to switch between base+boost)
