Switch reset pin of ov8856 node from GPIO_ACTIVE_HIGH to GPIO_ACTIVE_LOW,
this issue prevented the ov8856 from probing properly as it does not respond
to I2C messages.

Fixes: d4919a44564b ("arm64: dts: qcom: sdm845-db845c: Add ov8856 & ov7251
camera nodes")

Please do use GPIO_ACTIVE_LOW as the argument...
