Setting up a "trigger master" so the hardware can handle NCO profile switching automatically. This means we can do frequency hopping on a timer instead of manually toggling GPIOs or registers every time. Key changes: -Added FFH_TRIG_PERIOD to sysfs. You can now set a hop period in $F_s$ cycles. If you write 0, it defaults to 2000 cycles to keep things sane. -Added cnco_trig_by_tmaster() and fnco_trig_by_tmaster(). These kick in automatically when you set the mode to TRIG_AUTO. -The apollo API won't let us update NCO frequencies one by one. I’ve switched to a vector-based approach where we cache frequencies in an array and push the whole batch at once using apollo_cnco_init_profile_load_func(). -Added a timestamp reset before the auto-trigger starts so you don’t get a random hop right at the beginning. -Moved ad9088_read_gpio_hop_array() to the end of the file and added forward declarations to clean up the flow. The trigger master defaults to 2000 Fs cycles if userspace writes 0, providing a reasonable default for automated frequency hopping sequences. Tested with CNCO and FNCO profile switching in TRIG_AUTO mode. Signed-off-by: Oscar Magana Pantoja <Oscar.MaganaPantoja@analog.com>
