workqueue: ROGUE workers are UNBOUND workers

Currently, WORKER_UNBOUND is used to mark workers for the unbound
global_cwq and WORKER_ROGUE is used to mark workers for disassociated
per-cpu global_cwqs.  Both are used to make the marked worker skip
concurrency management and the only place they make any difference is
in worker_enter_idle() where WORKER_ROGUE is used to skip scheduling
idle timer, which can easily be replaced with trustee state testing.

This patch replaces WORKER_ROGUE with WORKER_UNBOUND and drops
WORKER_ROGUE.  This is to prepare for removing trustee and handling
disassociated global_cwqs as unbound.

defconfig: add all devices w/o HDMI support

Some devices have issues with the HDMI slot. The device thinks HDMI cable is plugged and the kernel tries constanly to read the screen's EDID information. This and also the procession of all audio through the HDMI port eats battery. Build all device kernels also without HDMI support - also useful for thos who donÄt use HDMI or donÄt own such cables.
add a testing build script to find building error more quick.
build script: add option to choose from build with or without HDMI support
hdmi_toggle: fix sysfs interface to toggle hdmi on the fly.

- Disable sound
- Disable panel
- Disable screen output
- Disable annoying edid reading for the case the device thinks a HDMI cable is plugged - even if there's no cable plugged!

Introduce a persistant drop to disable/enable hdmi constantly
defconfig: Enable hdmi_toggle, enable thermal_sys module, thermal_framework_hwmon

Thermal Framework reduces heat by software feature (scaling frequency to lower limits, etc)
The thermal_sys (tghermal management sysfs driver) is an addition taken from 3.4 kernel.

Thermal Framework proiveds overall power savings and limits IC damage by thermal throttling
