F75303: Set fake temperature
Add new console command `f75303` to set fake temperature for F75303.
Usage:
f75303 <index> <value>|off
<index>
0: F75303_Local
1: F75303_Remote1
2: F75303_Remote2
<value>
integer from 0 to 100 (Celsius degree)
"off"
turn off fake temperature mode, back to normal
BUG=none
BRANCH=master
TEST=fan target speed can follow fake temperature, make buildall pass
