[media] s5p-fimc: Add device tree based sensors registration
The sensor (I2C and/or SPI client) devices are instantiated by their corresponding control bus drivers. Since the I2C client's master clock is often provided by a video bus receiver (host interface) or other than I2C/SPI controller device, the drivers of those client devices are not accessing hardware in their driver's probe() callback. Instead, after enabling clock, the host driver calls back into a sub-device when it wants to activate them. This pattern is used by some in-tree drivers and this patch also uses it for DT case. This patch is intended as a first step for adding device tree support to the S5P/Exynos SoC camera drivers. The second one is adding support for asynchronous sub-devices registration and clock control from sub-device driver level. The bindings shall not change when asynchronous probing support is added.
