raspberry pi 4: cpufreq support

The submitter notes that the bcm2835_cpufreq driver really just needs the
rpi4 compat string added to it; powerd subsequently works and the dev.cpu.0
sysctl values look sane and can be successfully manipulated.

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

is "brcm,bcm2835", add it to the compatible list of bcm2835_cpufreq.

Tested On: RPi1 Model B

Note that the default Das U-Boot FDT does not include a cpus clause
so actually adding a bcm2835_cpufreq device requires adding a FDT
overlay defining the cpu.

[rpi] rpi3 should use the same cpufreq logic as rpi2, not rpi-b

RPi3 cpufreq is more like that on RPi2. Setting arm frequency
above min (say, "sysctl hw.cpufreq.arm_freq=600000001") turns on
turbo mode, and the firmware automatically raises voltage, sets
frequency to max 1200MHz, and throttle when overheat, etc.

Swap if/else parts and use SOC_BCM2835 def so RPi3 can share the
same cpufreq logic as RPi2, instead of falling to that for RPi.
