net: phy: realtek: Fix setting of PHY LEDs Mode B bit on RTL8211F
The current implementation incorrectly sets the mode bit of the PHY chip.
Bit 15 (RTL8211F_LEDCR_MODE) should not be shifted together with the
configuration nibble of a LED- it should be set independently of the
index of the LED being configured.
As a consequence, the RTL8211F LED control is actually operating in Mode A.
Fix the error by or-ing final register value to write with a const-value of
RTL8211F_LEDCR_MODE, thus setting Mode bit explicitly.
