rtsx_usb_sdmmc module uses the LED classdev if available, but the code
failed to consider the situation that it is built-in and the LED classdev is a
module, leading to following linking error:
LD init/built-in.o
drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_remove':
rtsx_usb_sdmmc.c:(.text+0x2a018e): undefined reference to
`led_classdev_unregister'
drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_probe':
rtsx_usb_sdmmc.c:(.text+0x2a197e): undefined reference to
`led_classdev_register'
Fix by excluding such condition when defining macro RTSX_USB_USE_LEDS_CLASS.
