Instead of using own error or success codes, the PCMCIA code should rely on
the generic return values. Therefore, replace all occurrences of CS_SUCCESS
with 0.

By calling pcmcia_loop_config(), a pcmcia driver can iterate over all

Ron Minnich noticed that guest userspace gets a GPF when it tries to int3:

The original "Pass the bus number we expect the S3C24XX SPI driver to
attach to via the platform data." [1] patch was mis-sent, and missed two
important parts of the diff, which was to actually set the bus_num field
and add the relevant field to the platform data.

The previous commit 50f426b5 promised to
add a bus_num field, but failed to include the two hunks that added this
field to include/asm-arm/arch-s3c2410/spi.h and then pass it to the spi
core when creating the new master field in drivers/spi/spi_s3c24xx.c.

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.
