Current code use dev_err to output log if kernel cannot bind any one
7+
sensor in initialization. This is a strictly checking to make sure all
8+
four sensors have to be used for system.
9+
10+
After enable thermal power allocator, usually system only use one sensor
11+
for multiple actors. This patch changes to use dev_dbg so that avoid
12+
confusion in boot log, and remove duplicate printing log.

5+
tree
6+
7+
Some Mali 450 Utgard GPU platform integration files like
8+
the HiKey need a custom Device Tree entry. This config
9+
option is to disable the standard driver code that expects
10+
things in the device tree which conflict with what the
11+
platform files need.
12+
13+
This is only an interim solution, tne platform files should
14+
really be tidied-up to enable the standard device tree
15+
instead (would require adding more IRQ and other resources).
