While checkpatch another patch I got a:
"WARNING: msleep < 20ms can sleep for up to 20ms"
The datasheet of at86rf231 and at86rf212 says a minimum delay for reset
pulse width and spi access latency after reset is 625 nanoseconds.
This patch removes the 1 milliseconds sleep and replace it with a 1
microseconds udelay which should be also okay for these devices.
