dptf: Get rid of CONFIG_DPTF_DEVICE_ORIENTATION
CONFIG_DPTF_DEVICE_ORIENTATION was added to indicate mode change to
the host to allow it to read the tablet mode flag from shared EC
memory and select the right DPTF table to load (if supported).
However, this config seems unnecessary because of the following
reasons:
1. Host sets SCI mask to indicate to the EC which events it wants to
process. Thus, even if the EC sets mode change flag, it will not be
notified to the host unless it supports mode change event.
2. Additionally, if host supports mode change event, but does not
support multiple DPTF tables, then EC ACPI code takes care of ensuring
that there is a thermal event handler present to reload tables.
3. CONFIG_DPTF_DEVICE_ORIENTATION was defined for almost all new x86
boards.
