[U-Boot] [PATCH v3] spi: mxc_spi: Fix double incrementing read pointer for unaligned buffers

[Jagannadha Sutradharudu Teki]

From: Timo Herbrecher <t.herbrecher at gateware.de>

If dout buffer is not 32 bit-aligned or data to transmit is not multiple
of 32 bit the read data pointer is already incremented on single byte reads.
