ARM: ux500: Provide SMSC911x fixed-regulator when not booting DT
The SMSC911x Ethernet chip requires a fixed-regulator in order to function correctly. We have previously provided a means to obtain this during a Device Tree boot, however nothing has been put into place when booting with a non-DT kernel. This patch aims to change that. Signed-off-by: Lee Jones <lee.jones@linaro.org> [Added a Kconfig select so the build does not break] Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
