[PATCH v2 0/2] iio: adc: ltc2309: Add LTC2305 read delay and optimize chip_info

[Carlos Jones Jr]

This series adds missing read delay support for the LTC2305 and optimizes
the chip_info structure for better memory safety and efficiency.

The LTC2305 requires a 1.6μs delay between I2C channel selection and
data read operations - a timing requirement identified by the hardware
designer that wasn't captured in the initial LTC2305 support
(commit 8625d418d24b ("iio: adc: ltc2309: add support for ltc2305")).

Additionally, the chip_info structure is enhanced with __counted_by_ptr()
annotation for improved bounds checking and reorganized to minimize
padding.

Changes in v2:
- Split into two logical patches as suggested by Andy Shevchenko:
  * Patch 1: Read delay functionality
  * Patch 2: Structure optimization
- No code changes from v1, only reorganization
