Paulo noticed that we don't enable RPS interrupts via PM_IER in gen6_enable_rps_interrupts(). This wasn't a problem so far, since the only place we disabled RPS interrupts was during system/runtime suspend and after that we reenable all interrupts in the IRQ pre/postinstall hooks. In the next patch we'll disable/reenable RPS interrupts during GPU reset too, but not call IRQ uninstall, pre/postinstall hooks, so there the above wouldn't work. The logical place for programming PM_IER is gen6_enable_rps_interrupts() and this also makes the function more symmetric with gen6_disable_rps_interrupts(), so move the programming there from the postinstall hooks. Note that these changes don't affect the ILK RPS interrupt code, which could be sanitized in a similar way. But that can be done as a follow-up.
