media: i2c: thp7312: select CONFIG_FW_LOADER

The recently added driver uses the firmware loader mechanism but causes
a link failure when that is in a loadable module while thp7312 itself
is built-in:

arm-linux-gnueabi-ld: drivers/media/i2c/thp7312.o: in function `thp7312_probe':
thp7312.c:(.text+0x4164): undefined reference to `firmware_upload_register'

Select the required Kconfig symbol. Note that the driver specifically
needs the firmware upload interface that is controlled by CONFIG_FW_UPLOAD,
but there is no link failure when that is disabled because the interfaces
are stubbed out here.
