Subject: [PATCH 5/9] spi_mpc83xx: Fix checkpatch issues

Checkpatch is spitting errors when seeing the rename patch, so fix
the errors prior to moving.

Following errors and warnings were fixed:

WARNING: Use #include <linux/io.h> instead of <asm/io.h>
#1027: FILE: drivers/spi/spi_mpc8xxx.c:37:
+#include <asm/io.h>

ERROR: "foo * bar" should be "foo *bar"
#1111: FILE: drivers/spi/spi_mpc8xxx.c:121:

ERROR: "foo * bar" should be "foo *bar"
#1135: FILE: drivers/spi/spi_mpc8xxx.c:145:
+       const type * tx = mpc83xx_spi->tx;                      \

WARNING: suspect code indent for conditional statements (16, 25)
#1504: FILE: drivers/spi/spi_mpc8xxx.c:514:
+               while (((event =
[...]
+                        cpu_relax();

Following warnings were left over, since fixing them will
hurt the readability. We'd better fix them by lowering
the indentation level by splitting mpc83xx_spi_work function
into two parts.

WARNING: line over 80 characters
#1371: FILE: drivers/spi/spi_mpc8xxx.c:381:
+                                       status = mpc83xx_spi_setup_transfer(spi, t);

WARNING: line over 80 characters
#1392: FILE: drivers/spi/spi_mpc8xxx.c:402:
+                               mpc83xx_spi_chipselect(spi, BITBANG_CS_INACTIVE);
