During ISH DMA enabling, some platforms (such as EHL) don't support cache snooping, driver needs involve clflush_cache_range API which isn't supported by all archs (such as ARM). Considering ISH only exists on Intel platforms, add the dependence in Kconfig to avoid build warnings or errors on other archs.

The Integrated Sensor Hub (ISH) enables the ability to offload
|
|
sensor polling and algorithm processing to a dedicated low power
|
|
processor in the chipset. This allows the core processor to go into
|
|
low power modes more often, resulting in the increased battery life.
|
|
The current processors that support ISH are: Cherrytrail, Skylake,
|
|
Broxton and Kaby Lake.

|
Say Y here if you want to support Intel ISH. If unsure, say N.
