[PATCH 04/16] drm/i915: Drop has_rc6p from device info

[José Roberto de Souza]

No need to have this parameter in intel_device_info struct
as it was only supported in sandybridge and ivybridge platforms.

As a side effect of the of removal this flag, it will not be printed
in dmesg during driver load anymore and developers will have to rely
on to check the macro and compare with platform being used and IP
versions of it.

v2:
- simplified check
