Yegor Yefremov 2f440ad7b5 hciattach: fix serial speed setting for wl1271
override speed setting if firmware script issues serial settings command,
otherwise the value given in the firmware script will be overridden.

Example:

hciattach /dev/ttyO1 texas 115200

will fail, because /dev/ttyO1 will be opened with 115200 b/s, then
the firmware script will set the buadrate to 3000000 b/s, after UART init
hciattach.c will set the baudrate to 115200, so communication is broken.

The only correct way is to set both speeds:

hciattach -s 115200 /dev/ttyO1 texas 3000000

With this patch only initial speed must be specified. The former semantic
will be preserved in case the firmware script doesn't provide serial
settings action.

Tested with wl1271 and firmware TIInit_7.2.31.bts
