[PATCH v3 0/3] iio: adc: xilinx-ams: refactor alarm handling to table-driven design

[Guilherme Ivo Bozi <guilherme.bozi@usp.br>]

This series addresses significant code duplication in alarm handling
logic across the Xilinx AMS IIO driver.

To address this, the series introduces a centralized table-driven
mapping (alarm_map) that replaces multiple switch statements spread
across the driver.

This improves:
- maintainability (single source of truth for mappings)
- readability (removes repeated switch logic)
- extensibility (new alarms require only table updates)

No functional changes are intended.

Series overview:
- Patch 1: fix out-of-bounds channel lookup 
- Patch 2: convert mutex handling to guard(mutex) 
- Patch 3: introduce table-driven alarm mapping

v1 -> v2:
- Fixed Fixes tag format
- Replaced AMS_ALARM_INVALID with AMS_ALARM_NONE
- Changed alarm_map base_offset type

v2 -> v3:
- Replace 'i >= num_channels' with 'i == num_channels'
- Add missing trailing comma in alarm_map array initializer
