Refactors LT PHY PLL handling to route it through the existing
DPLL framework.
Currently, LT PHY PLL control lives in standalone code paths separate
from the DPLL infrastructure. This results in duplicated logic and
special-case handling in the display enable/disable paths.
The series consolidates LT PHY PLL handling under the current DPLL
abstractions. The changes are mechanical in nature and do not introduce
any new DPLL infrastructure.
Intended behavior is unchanged.
Summary:
- Move LT PHY PLL state handling under DPLL structures
- Wire LT PHY PLL enable/disable through DPLL hooks
- Remove redundant standalone LT PLL code paths
