sh_eth: Change platform check to CONFIG_ARCH_RENESAS

Since commit 9b5ba0d ("ARM: shmobile: Introduce ARCH_RENESAS")
is CONFIG_ARCH_RENESAS a more appropriate platform check than the legacy
CONFIG_ARCH_SHMOBILE, hence use the former.

Renesas SuperH SH-Mobile SoCs are still covered by the CONFIG_CPU_SH4
check.

This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near
future.
