iwlwifi: remove the code under IWLWIFI_PCIE_RTPM

Browse Source 
This flag should never be set unless integration work with the
platform is done.  We don't support any platforms officially and don't
plan to do so in the near future, so we can remove this option
entirely in order to avoid having it enabled by mistake.

This has been marked with "depends on EXPERT", so there shouldn't be
many systems running with it set.  And, if there are systems, they
should not be using this flag.

expect incoming broadcasts for their normal operations.

bool "Enable runtime power management mode for PCIe devices"
depends on IWLMVM && PM && EXPERT
help
Say Y here to enable runtime power management for PCIe
devices. If enabled, the device will go into low power mode
when idle for a short period of time, allowing for improved
power saving during runtime. Note that this feature requires
a tight integration with the platform. It is not recommended
to enable this feature without proper validation with the
specific target platform.
If unsure, say N.
