[U-Boot] [PATCH] net: designware: fix unused warning when CONFIG_DW_AUTONEG is enabled

The ctrl variable is only used when autoneg support is disabled, so only declare it under those conditions to avoid an unused variable warning.

When CONFIG_DW_SEARCH_PHY is disabled, the local phy_addr variable never gets initialized causes random behavior at runtime and a gcc warning. So set it by default to the stored phy address.

Applied (with minimal changes to the commit message which is missing a 'which" or so), thanks.
Best regards,
