Subject: [PATCH 0/4] Add eMMC PHY support for Axiado AX3000 SoC

Axiado AX3000 SoC contains Arasan PHY which provides the interface to the
HS200 eMMC controller.

This series includes:
1. Add bindings for Axiado AX3000 eMMC PHY
2. Add Axiado AX3000 eMMC phy driver
3. Update MAINTAINERS for the new driver
4. Update Axiado AX3000 device tree

Changes: (The previous version was mixed with Host driver, so I separate
the PHY driver as a new thread)
- Fix property order in required section to match properties section
- Fixed example to use lowercase hex and proper node naming
- Removed wrapper functions, use readl/writel directly
- Replaced manual polling loops with read_poll_timeout macro
- Used devm_platform_ioremap_resource instead of separate calls
- Removed unnecessary of_match_node check
- Used dev_err_probe for error reporting
- Added proper Kconfig dependencies (ARCH_AXIADO || COMPILE_TEST)
- Fixed various coding style issues
- Link to previous patches: https://lore.kernel.org/all/20251222-axiado-ax3000-add-emmc-host-driver-support-v1-0-5457d0ebcdb4@axiado.com/
