drm/i915/psr: Consider SCL lines when validating vblank for wake latency

Panel Replay and PSR2 selective update require sufficient vblank duration
to accommodate wake latencies. However, the current
wake_lines_fit_into_vblank() logic does not account for the minimum
Set Context Latency (SCL) lines.

Separate out _intel_psr_min_set_context_latency() to compute the minimum
SCL requirement based on platform and feature usage.

The alpm_config_valid() helper is updated to pass the necessary context for
determining whether Panel Replay or PSR2 selective update is enabled.

v2: While calling alpm_config_valid() for selective_update use false flag
    instead of has_panel_replay. (Jouni)
v3: Correct ordering of the panel_replay, sel_update flags. (Jouni)
