Subject: [PATCH net-next] net: phy: at803x: add missing dependency on CONFIG_REGULATOR

Compilation fails on PPC targets as CONFIG_REGULATOR is not set and
drivers/regulator/devres.c is not compiled in while functions exported
there are used by drivers/net/phy/at803x.c. Here's the error log:

  LD      .tmp_vmlinux1

drivers/net/phy/at803x.c:294: undefined reference to `.rdev_get_drvdata'
