Rather than each driver having its own way to allocate a SPI slave,
use the new allocation function everywhere. This will make it easier
to extend the interface without breaking drivers.

Added posted writes (read after writes) to effect the
change immediately for channel confiuration and channel
enable register
Disable the channel to purge receieve data in TX_ONLY
mode transfer otherwise rx data will get affected by
the next immediate RX_ONLY mode transfer
Wait for the EOT bit to be set after last byte has been
loaded to TX shift register in the the TX_ONLY mode.This
ensures TX data has been completely shifted out
Disable the channel in RX_ONLY mode before reading the
last data from RXX register to prevent the SPI slave
to transmit next word

D0/D1 Swapped or not is a board property, not anything specific to
the am33xx SoC, so add a custom define for it.
At the same time correct the bit handling for the swapped mode
(DPE0 should be cleared and SI/DPE1 set).

Implementation of receive-transmit mode for
omap3 MCSPI.
Introduces full duplex communication, needed by
some spi devices (such as enc28j60).
