Revert "drivers: iio: imu: decreased the ASM buffer size and IAM timeout"
This reverts commit 1a7f55c5beb6fcd49307ccf2541e8be6b104a169.
This patch allows driver to read the max number of samples from
sensor chip on each interrupt by increasing frequency of interrupt
which in turn reduce the load on cpu unlike earlier patch.
