This is an attempt to finish Martin's great work on the bcm2835
thermal driver. It includes now all Eduardo's suggestions and the
explanations from the Raspberry Pi forum [1].

ChangeLog:
V1 -> V2: added specific settings depending on compatiblity
added trip point based on register
setting up ctrl-register if HW is not enabled by firmware
as per recommendation of Eric (untested)
check that clock frequency is in range
(1.9 - 5MHz - as per comment in clk-bcm2835.c)
V2 -> V4: moved back to thermal (not using bcm sub-directory)
set polling interval to 1second (was 0ms, so interrupt driven)
V5 -> V6: added correct depends in KConfig
removed defined default for RESET_DELAY
removed obvious comments
clarify HW setup comments if not set up by FW already
move clk_prepare_enable to an earlier stage and add error handling
clarify warning when TS-clock runs out of recommended range
clk_disable_unprepare added in bcm2835_thermal_remove
added comment on recommended temperature ranges for SOC
V6 -> V7: removed depends on ARCH_BCM2836 || ARCH_BCM2837 in Kconfig
V7 -> V8: rebased
V8 -> V9: moved to use the thermal framework offset and slope in
thermal_zone_parameters as per request
V9 -> V10: implement support for thermal zone descriptor, define offset and
slope within DT, apply forum explanations, replace symbolic with octal
permissions
V10 -> V11: fix parse issue in bcm2837.dtsi, fix probing and remove unused tzp
(sorry about this crap)
