[PATCH v1 2/3] net: mtk_eth: an8855: enable link error recovery

[Mikhail Zhilkin <csharper2005@gmail.com>]

Sync the Link Error Recovery configuration with the upstream Linux
driver.

Currently, the U-Boot driver explicitly clears the
AN8855_RG_LINK_ERRO_EN bit (bit 23) in the AN8855_RX_CTRL_26 register
during SGMII initialization. Setting this bit instead of clearing it
matches the Linux driver behavior, allowing the MAC/PCS to gracefully
recover from momentary link errors on marginal hardware rather than
dropping packets or the entire link.
