Matteo Golin b49b62a733 analog/ads1115: Speed up channel measurement delays 
The ADS1115 driver uses the `nxsig_usleep()` function to sleep for a
65us delay, but with a 1ms tick resolution and the context-switching
overhead, this is much more than 1ms. Introducing `up_udelay` (even with
a larger duration because of the unreliability of busy-waiting) speeds
up sampling noticeably.
