This patch series adds I2C support to Andes platform, such as AE350 and
QiLai SoC.

Changes in v2:
- ATCIIC100 is the hardware name for the Andes I2C controller and was used
throughout v1. However, since Device Tree bindings should reflect the hardware
identity and driver/config naming typically follows the i2c-<soc/platform>
convention, this version replaces occurrences of "atciic100" with more
appropriate names, such as "i2c-andes" or "andes_i2c," to align with upstream
standards.
- Updated cover letter title and the description.
- Rebased on andi.shyti/i2c/i2c-host-next.
- (1/4)
- Updated the title and the description of the patch.
- Specified what the hardware is, and modify the title and compatibles. (Krzysztof)
- Corrected device register size.
- (2/4)
- Updated the title and the description of the patch.
- Replaced the readl/writel operations with regmap APIs.
- Replaced all occurrences of atciic100 with proper names.
- Used module_platform_driver() to initialize. (Andi)
- Moved CONFIG_I2C_ANDES (CONFIG_I2C_ATCIIC100 in v1) to the
"Embedded system I2C/SMBus host controller drivers" section.
- Made CONFIG_I2C_ANDES depend on ARCH_ANDES
- (3/4) (new)
- Added an entry to the MAINTAINERS file.
- (4/4) (new)
- Added the I2C node to QiLai DTS.
