Subject: [PATCH net-next 11/11] net: dsa: Kconfig: Enable support for RZ/T2H and RZ/N2H SoCs

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Update the Kconfig entry for the Renesas RZ/N1 A5PSW Ethernet switch
driver to depend on ARCH_RENESAS instead of ARCH_RZN1. This allows
the driver to be built for other Renesas SoCs that integrate a similar
Ethernet switch IP, such as RZ/T2H and RZ/N2H.

Also update the help text and prompt to reflect support for the ETHSW
variant used on these SoCs.
