The i.MX 93 ADC calibration parameters are configurable in the MCR
(Main Configuration Register). One can tweak bits:

 - MCR[AVGEN]: Enable calibration averaging function,
 - MCR[NRSMPL]: Select number of calibration samples,
 - MCR[TSAMP]: Select sample time of calibration conversions, 

Make it possible to configure those parameters via the corresponding
device-tree properties.

This patch series is based on the one we submitted in March 2024:
https://lore.kernel.org/linux-arm-kernel/20240320100407.1639082-1-andrej.picej@norik.com/

Changes since the original submission:
- rebase on linux-next
- reorder patches (bindings before users)
- fix checkpatch errors
- reword commit subject & body
- implement feedback from reviewers
