Exynos: SPI: Fix reading data from SPI flash

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.
