net: ethernet: mtk_eth_soc: fix typo for declaration MT7988 ESW capability

[ Upstream commit 1bdea6fad6fb985ff13828373c48e337c4e939f9 ]

Since MTK_ESW_BIT is a bit number rather than a bitmap, it causes
MTK_HAS_CAPS to produce incorrect results. This leads to the ETH
driver not declaring MAC capabilities correctly for the MT7988 ESW.
