Subject: [net-next PATCH 1/2] net: phy: qcom: qca808x: fix logic error in LED brightness set

In switching to using phy_modify_mmd and a more short version of the
LED ON/OFF condition in later revision, it was made a logic error where

value ? QCA808X_LED_FORCE_ON : QCA808X_LED_FORCE_OFF is always true as
value is always OR with QCA808X_LED_FORCE_EN due to missing ()
resulting in the testing condition being QCA808X_LED_FORCE_EN | value.

Add the () to apply the correct condition and restore correct
functionality of the brightness ON/OFF.
