SPI recieve and transfer code in exynos_spi driver has a logical bug.
We read data in a variable which can hold an integer. Then we assign
this integer 32 bit value to another variable which has data type uchar.
Latter represents a unit of our recieve buffer. Everytime when we write
a value to our recieve buffer we step ahead by 4 units when actually we
wrote to one unit. This results in the loss of 3 bytes out of every 4
bytes recieved. This patch intends to fix this bug.

This mirrors the conventions used in other SPI drivers (kirkwood,
davinci, atmel, et al) where the din/dout buffer can be NULL when the
received/transmitted data isn't important.  This reduces the need for
allocating additional buffers when write-only/read-only functionality is
needed.

In the din == NULL case, the received data is simply not stored.  In the
dout == NULL case, zeroes are transmitted.
