The checkpatch.pl warns about two `udelay(x)` calls, one of 100
microseconds, and one of 10 microseconds. The 100 microseconds one is
used when waiting for FPGA to become ready to accept firmware, and is
not that critical, so replace it with a call to `usleep_range(100,
1000)`. The 10 microseconds one is called as each 16-bit word of
firmware data is written. A longer sleep would slow down firmware
loading, so leave it alone.
