Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled
for virtual targets such as malta or potent ones like x86.
This saves up to 4KB of uncompressed kernel size and significantly
decreases CPU load under certain workloads.

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.

With cpufreq disabled, the CPU stays locked at the frequency set by the
bootloader. This severely degrades performance as the bootloader sets
the CPU at the lowest frequency by default.
Enable cpufreq for all subtargets and use the ondemand governor.
Tested bcm2708 on RPi0W. Tested bcm2709 and bcm2710 on RPi3.

This fixes:
Thermal sensors on bcm2835 SoC (BCM2835_THERMAL) [N/m/y/?] (NEW) aborted!
This symbol depends on ARCH_BCM2835 so it should be OK to disable it at
brcm2708 target only.

As usual these patches were extracted and rebased from the raspberry pi repo:
https://github.com/raspberrypi/linux/tree/rpi-4.9.y
- Remove led1 from diag.sh for RPi3 since it causes boot issues.
- Fix modules.mk typos.

This adds support for Raspberry Pi 3 on the bcm2709 subtarget, in order to
keep 32 bit image support when 64 bit support is added on bcm2710 subtarget.

- random-bcm2708 and spi-bcm2708 have been removed.
- sound-soc-bcm2708-i2s has been upstreamed as sound-soc-bcm2835-i2s.
Let's keep linux 4.1 for a while, since linux 4.4 appears to have some issues
with multicast traffic on RPi ethernet:
