[PATCH] net: sun8i-emac: Fix pinmux setup for Allwinner H5

Commit eb5a2b671075 ("net: sun8i-emac: Determine pinmux based on SoC,
not EMAC type") switched the pinmux setup over to look at
CONFIG_MACH_SUN* symbols, to find the appropriate mux value.
Unfortunately this patch missed to check for the H5, which is
pin-compatible to the H3, but uses a different Kconfig symbol (because
it has ARMv8 vs. ARMv7 cores).

Replace the pure SUN8I_H3 symbol with the joint SUNXI_H3_H5 one, which is
there to cover the peripherals common to both SoCs.
Also explicitly list each supported SoC, and have an error message in the
fallback case, to avoid those problems in the future.

This fixes Ethernet support on all H5 boards.
