[PATCH] net: mdio: mscc-miim: Add depend of REGMAP_MMIO on MDIO_MSCC_MIIM

[Tianchen Ding]

There's build error while CONFIG_REGMAP_MMIO is not set
and CONFIG_MDIO_MSCC_MIIM=m.

ERROR: modpost: "__devm_regmap_init_mmio_clk"
[drivers/net/mdio/mdio-mscc-miim.ko] undefined!

Add the depend of REGMAP_MMIO to fix it.
