[U-Boot] [PATCH] SPI: fixup typo in omap2_spi.c

  regs->channel[] is an array of registers in SoC. It is indexed by CS#
  Fixup the typo which will cause the index error when accessing the hardware.

  In the all other code, regs->channel[] is indexed by 'priv->cs', so I think
  it is reasonable to fix that wrongly register accessing.
