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.
