[PATCH v10 4/5] phy: move and rename Airoha PCIe PHY driver to dedicated directory

[sashiko-bot at kernel.org]

Thank you for your contribution! Sashiko AI review found 4 potential issue(s) to consider:
- [Low] The driver Kconfig symbol, file names, and platform driver name are incorrectly renamed using the 'AN7581' prefix instead of 'EN7581', creating a mismatch with the hardware name and device tree bindings.
- [Low] The include guard in `phy-an7581-pcie-regs.h` was not updated after the file was renamed.
- [Low] Incorrect SPDX-License-Identifier comment style for a C header file.
- [Low] The newly added `Kconfig` and `Makefile` for the `drivers/phy/airoha/` directory are missing from the `MAINTAINERS` file.

phy: move and rename Airoha PCIe PHY driver to dedicated directory

This commit moves the PCIe PHY driver for the Airoha AN7581 SoC to a dedicated
directory to keep the generic PHY directory tidy. It also renames the driver
and files to include the specific SoC name in preparation for adding AN7583
support, and updates the Kconfig symbol accordingly.

[Severity: Low]
This isn't a bug, but there might be a typo in the commit message. Is the
SoC name EN7581 instead of AN7581, given the existing device tree bindings
mention en7581?

[Severity: Low]
By explicitly listing only the source files, the newly added Kconfig and
Makefile in the drivers/phy/airoha/ directory are left without a maintainer
mapping. Would it be better to use a directory wildcard like
F: drivers/phy/airoha/ to include the new build files?

[Severity: Low]
Does this Kconfig symbol and prompt incorrectly use the AN7581 prefix
despite the SoC hardware and device tree binding being named EN7581?

[Severity: Low]
Does this change to a C++ style line comment violate the kernel's SPDX
license identifier rules for C header files, which require the /* ... */
block comment style?

[Severity: Low]
Also, since this file was renamed, does the include guard further down in the
file (currently #ifndef _PHY_AIROHA_PCIE_H) need to be updated to match the
new filename?

[Severity: Low]
Does this platform driver name incorrectly use the misspelled an7581 prefix
instead of en7581?
