    bluez: Correct the timer count for bcm43xx firmware download
    
    bcm43xx failed as time out for firmware downloading.
    The root cause is that it need wait 50ms to download firmware,
    but the value of 50us is set to the timer.

+Subject: [PATCH] hciattach: bcm43xx: fix the delay timer for firmware download
+
+From the log in .bcm43xx_load_firmware():
+        /* Wait 50ms to let the firmware placed in download mode */
+        nanosleep(&tm_mode, NULL);
+
+But timespec tm_mode is real is 50us. Correct the delayed timer count.
