Subject: [PATCH net-next] net: pcs: Kconfig: Fix unmet dependency warning

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

Fix the Kconfig dependencies for PCS_RZN1_MIIC to avoid the unmet direct
dependency warning when enabling DWMAC_RENESAS_GBETH. The PCS driver is
used on multiple Renesas SoCs including RZ/N1, RZ/N2H and RZ/T2H, but the
existing condition only allowed ARCH_RZN1, ARCH_R9A09G077, or
ARCH_R9A09G087. This conflicted with the GBETH/GMAC driver which selects
PCS_RZN1_MIIC under ARCH_RENESAS.

Update the dependency to ARCH_RENESAS || COMPILE_TEST so that the PCS
driver is available on all Renesas platforms.

Fixes: 08f89e42121d ("net: pcs: rzn1-miic: Add RZ/T2H MIIC support")
