Jiyong Park 5067fe1a19 Move thermal HAL to vendor partition 
In order to build generic system image that is agnostic to SoC or
device, HALs should be moved from system partition to vendor
partition.

Bug: 34826389, 35743509
Test: build & run and check whether the HAL is loaded from
/vendor/lib[64]/hw.
$ su; lsof | grep thermal.

Default (and possibly architecture dependents) HAL modules go here. 


libhardware.so eventually should contain *just* the HAL hub
(hardware.c), everything in it should be rewritten as modules.

Modules are .so in /system/libs/hw/ and have a well defined naming
convention:

    /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.product.board>.so
    /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.board.platform>.so
    /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.arch>.so
    /system/libs/hw/<*_HARDWARE_MODULE_ID>.default.so

They also have a well defined interface which lives in include/hardware/.

A module can have several variants: "default", "arch" and "board", and they're
loaded in the "board", "arch" and "default" order.
The source code for the "board" variant, usually lives under partners/...

The source code for "default" and "arch" would usually
live under hardware/modules/.
