i7300_idle: Remove this driver

In preparation for removing the idle_notifier, remove its only user, the
i7300_idle driver.

i7300_idle was deployed in 2008 to reduce idle memory power on systems
using the i7300 chipset. The driver worked by throttling the
fully-buffered DIMMs during idle periods using the IOAT DMA engine.

The driver ran only on the i7300 chip-set, and no other hardware has used
this mechanism. The driver no longer has a maintainer.

Removing this driver will increase idle power on i7300 systems when they
run the new kernel without the driver.

drivers/idle: remove depends on CONFIG_EXPERIMENTAL

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

intel_idle: disable module support

Right now the module capability is cauing more trouble
than it is worth. At least one distro built intel_idle as a module
where it lost the init race with ACPI, making it useless.

Make intel_idle bool so that if you select it, you will use it.

We can restore module capability after cpuidle is enhanced
to handle run-time changing of idle drivers.

intel_idle: native hardware cpuidle driver for latest Intel processors

intel_idle: native hardware cpuidle driver for latest Intel processors

This EXPERIMENTAL driver supersedes acpi_idle on
Intel Atom Processors, Intel Core i3/i5/i7 Processors
and associated Intel Xeon processors.

It does not support the Intel Core2 processor or earlier.

For kernels configured with ACPI, CONFIG_INTEL_IDLE=y
allows intel_idle to probe before the ACPI processor driver.
Booting with "intel_idle.max_cstate=0" disables intel_idle
and the system will fall back on ACPI's "acpi_idle".

Typical Linux distributions load ACPI processor module early,
making CONFIG_INTEL_IDLE=m not easily useful on ACPI platforms.

intel_idle probes all processors at module_init time.
Processors that are hot-added later will be limited
to using C1 in idle.

The Intel 7300 Memory Controller supports dynamic throttling of memory which can
