[media] nuvoton-cir: Activate PNP device when probing
On certain motherboards (mainly Intel NUC series) bios keeps the Nuvoton CIR device disabled at boot. This patch adds a call to kernel PNP layer to activate the device if it is not already activated. This will improve the chances of the PNP probe actually succeeding on Intel NUC platforms.
