drm/st7735r: Fix module autoloading for Okaya RH128128T

The SPI core always reports a "MODALIAS=spi:<foo>", even if the device was
registered via OF. This means that the st7735r.ko module won't autoload if
a DT has a node with a compatible "okaya,rh128128t" string.

In that case, kmod expects a "MODALIAS=of:N*T*Cokaya,rh128128t" uevent but
instead will get a "MODALIAS=spi:rh128128t", which is not present in the
list of aliases:

  $ modinfo drivers/gpu/drm/tiny/st7735r.ko | grep alias
  alias:          of:N*T*Cokaya,rh128128tC*
  alias:          of:N*T*Cokaya,rh128128t
  alias:          of:N*T*Cjianda,jd-t18003-t01C*
  alias:          of:N*T*Cjianda,jd-t18003-t01
  alias:          spi:jd-t18003-t01

To workaround this issue, add in the SPI table an entry for that device.
