drm/i915/display: Sanitize PHY_C20_VDR_CUSTOM_SERDES_RATE/CONTEXT_TOGGLE flag macro
Move the PHY_C20_CONTEXT_TOGGLE flag's definition under the register containing
the flag and refer to the flag always by its name instead of a plain bit number.
v2: Amend commit log to match what the patch does. (Jani)
