dt-bindings: thermal: Drop db8500-thermal.txt
The binding is already defined in mfd/stericsson,db8500-prcmu.yaml and none
of 'the tripN.*' properties appear to be in use.

** Thermal node properties:
4
-
5
-
- compatible : "stericsson,db8500-thermal";
6
-
- reg : address range of the thermal sensor registers;
7
-
- interrupts : interrupts generated from PRCMU;
8
-
- interrupt-names : "IRQ_HOTMON_LOW" and "IRQ_HOTMON_HIGH";
9
-
- num-trips : number of total trip points, this is required, set it 0 if none,
10
-
if greater than 0, the following properties must be defined;
11
-
- tripN-temp : temperature of trip point N, should be in ascending order;
12
-
- tripN-type : type of trip point N, should be one of "active" "passive" "hot"
13
-
"critical";
14
-
- tripN-cdev-num : number of the cooling devices which can be bound to trip
15
-
point N, this is required if trip point N is defined, set it 0 if none,
16
-
otherwise the following cooling device names must be defined;
17
-
- tripN-cdev-nameM : name of the No. M cooling device of trip point N;
18
-
19
-
Usually the num-trips and tripN-*** are separated in board related dts files.
