7e99a6ba69 target: disable CONFIG_PROC_PAGE_MONITOR on most targets
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.

68e7a2a0b7 kernel: disable CONFIG_SG_POOL by default
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.

c454fab0f2 brcm2708: enable cpufreq
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.

da529d5410 brcm2708: disable CONFIG_BCM2835_THERMAL by default
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.

Fixes: 7d32caa61fb0 ("brcm2708: backport upstream sdhost controller driver")

- Remove led1 from diag.sh for RPi3 since it causes boot issues.
- Fix modules.mk typos.

buildbot fails to build without regmap, which I couldn't reproduce locally.
Hopefully this fixes it.
