Display got wrong rotation after hid_sensor_accel_3d is loaded

[AceLan Kao <acelan.kao@xxxxxxxxxxxxx>]

Hi all,

I'm working on a new platform which comes with an accelerator meter.
It's a STMicroelectronics LSM6DS3US accelerator meter, it doesn't use
st_sensors driver, but hid_sensor_accel_3d.
After hid_sensor_accel_3d is loaded, the display becomes upside down,
so I tried to add some code to make it become normal.(ACCEL_X should
have the same modification)

I don't know how to fix this in a correct way, please give me some hints.
Thanks.
