[PATCH] drm/i915/slpc: Update min_freq_softlimit when ignore_eff_freq is enabled

[Sk Anirban]

When slpc_ignore_eff_freq is enabled, min frequency is set to RPn but
min_freq_softlimit is not updated, causing sysfs to show stale
values.

Update min freq softlimit when ignore_eff_freq is successfully enabled.
