This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway.

Current code erroneously fill the last byte of R2 response with an undefined
value. In addition, the controller actually 'offloads' the last byte
(CRC7, end bit) while receiving R2 response and thus it's impossible to get the
actual value. This could cause mmc stack to obtain inconsistent CID from the
same card after resume and misidentify it as a different card.
Fix by assigning dummy CRC and end bit: {7'b0, 1} = 0x1 to the last byte of R2.

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.
