The Microchip KSZ DSA family now uses NET_DSA_MICROCHIP_KSZ_COMMON
for the common provider and NET_DSA_MICROCHIP_KSZ_SPI for SPI-attached
switches.

sama5_defconfig still enables the removed KSZ9477-specific symbols even
though SAMA5 device trees contain KSZ SPI switch consumers. Replace the
stale entries with the current provider symbols.

- add the coding-assistant disclosure

The Kconfig/provider mapping was reviewed statically; no SAMA5 kernel build
was performed.

Hi Claudiu,

I checked both changes. The first removed the KSZ9477 family option in
favour of the common option, and the second renamed the SPI provider.
Please include both tags with the patch:

Fixes: 07bca160469b ("net: dsa: microchip: common menuconfig for ksz series switch")
Fixes: 4658f2fe8fbc ("net: dsa: microchip: common ksz_spi_probe for ksz switches")

Thanks for the review.

Pengpeng
