disable deep sleep when Iota LEDB is on
TI's Iota chip docs say that CLK13M must be running in order for
LEDB to work, and practical experience on Mot C139 which uses
Iota LEDB for its keypad backlight concurs: if Calypso enters
deep sleep while the keypad backlight is turned on, the light
flickers visibly as the chipset goes into and out of deep sleep.
TI's original L1 sleep manager code had logic to disable deep sleep
when LT_Status() returns nonzero, but that function only works
for B-Sample and C-Sample LT, always returns 0 on BOARD 41 - no
check of Iota LEDB status anywhere. Change this code for our
current hardware: disable deep sleep when Iota LEDB has been
turned on through LLS.
