Fix Photosphere/Camera FCs

Photosphere is setting a few parameters "blindly"
while the API says it should check the device capabilities first.

On TF101 (and probably other devices) the camera HAL doesn't handle
FLASH_MODE & SCENE_MODE and so it sends the required RuntimeException
for these, which makes Photosphere FC the Camera app.

=> Fix: check device capabilities & ignore these 2 parameters if the device doesn't support them.

Fix based on following Team EOS patch: https://review.teameos.org/#/c/1598/
