[PATCH 1/5] iio: adis16480: make the burst_max_speed configurable

From: Ramona Gradinariu
Date: Tue Apr 23 2024 - 04:44:02 EST


With this, we can pass the maxixum spi burst speed to the
'ADIS16480_DATA()' macro. This is in preparation to support new devices
that have a different speed than the one used so far.
