[ARM] locomo: fix SPI register offset

The locomo spi registers are all defined in locomo.h as offsets
from the first spi register LOCOMO_SPI (0x60), which is itself
an offset from the locomo base address.  To correctly access
these registers LOCOMO_SPI must always be included in the
address calculation.

There are two places in locomo.c where this is not done.  The
first one, in locomo_suspend, actually results in a write to
LOCOMO_ST instead of LOCOMO_SPICT.  The second is in __locomo_probe
and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE.

Fix these by including LOCOMO_SPI in the calculation.
