[PATCH] n_r3964: fixed usage of HZ; removed bad include

Browse source 
Fix n_r3964 timeouts (hardcoded for 100Hz)

Also the include of <asm/termios.h> in 'n_r3964.h' is unnecessary and
prevents using the header file in any application that has to include
<termios.h> due to duplicate definition of 'struct termio'.
