[PATCH] net: phy: dp83869: fix memory corruption when enabling fiber

[Ingo van Lil]

When configuring the fiber port, the DP83869 PHY driver incorrectly
calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit
number (10). This corrupts some other memory location -- in case of
arm64 the priv pointer in the same structure.
