    jtag: ep93xx: replace nanosleep() with usleep()
    
    Both nanosleep() and usleep() are not compliant with C99 but are in
    use in OpenOCD code through the compile macro _GNU_SOURCE.
    While usleep() is widely used in the code, nanosleep() is used only
    in one file.
    
    Uniform the code base replacing nanosleep() with usleep().
