Subject: [PATCH net-next v2 1/4] net: dsa: yt921x: Use *_ULL bitfield macros for VLAN_CTRL

VLAN_CTRL should be treated as a 64-bit register. GENMASK and BIT
macros use unsigned long as the underlying type, which will result in a
build error on architectures where sizeof(long) == 32.

Replace them with unsigned long long variants.
