[U-Boot] [PATCH v2] net: Add option to disable fiber on M88E1111 PHY for PPC4xx
By defining CONFIG_M88E1111_DISABLE_FIBER boards can configure the M88E1111 PYH to disable fiber. This is needed for an upcoming PPC460GT based board, which has fiber/copper auto-selection enabled by default. This doesn't seem to work. So we disable fiber in the PHY register.

Applied to net repo.
