CONFIG_SG_POOL symbol is selected only by CONFIG_SCSI, since the last
one is disabled by default then disable CONFIG_SG_POOL by default too.
And explicitly enable it only for platforms that use CONFIG_SCSI.

The Pistachio target is a MIPS interaptiv based SoC developed by
Imagination Technologies. It includes blocks for i2c, spi, audio,
usb and WiFi.
This also adds the base support for the 'Creator Ci40 (marduk)'
device which uses the Pistachio SoC to create an IoT hub by
including Bluetooth, WiFi and 6lowpan on one board. Additionally 2x
Mikrobus ports are available to expand with further RF technologies
or add sensors. You can find out more here http://creatordev.io.
Note, this commit is just the initial board support hence the
following are not expected to work yet:
* WiFi
* Bluetooth
* 6lowpan
* Audio
* Mikrobus uarts, user leds (clock dependency of 6lowpan chip)
The aim of this commit is to essentially have the same level of
support that currently exists in the mainline kernel.

This adds kernel support for the Pistachio SoC and the Marduk (Ci40)
board which uses it.
Much of the code for Pistachio has been upstreamed however some
patches are still required to boot from the Marduk board:
* spi bug fixes
* dma bug fixes
* pistachio internal clock tree bug fixes
* spi-nand implementation
* dts based mtd device naming scheme
* dts backports and bug fixes
