mpc52xx_psc_spi: fix block transfer
The block transfer routine in the mpc52xx psc spi driver misinterpret the datasheet. According to the processor datasheet the chipselect is held as long as the EOF is not written. Theoretically blocks of any sizes can be transferred in this way. The old routine however writes an EOF after every word, which has the size of size_of_word. This makes the transfer slow. Also fixed some duplicate code.
