[PATCH] spi: Raise limit on number of chip selects

[Mark Brown <broonie@xxxxxxxxxx>]

As reported by Guenter the limit we've got on the number of chip selects is
set too low for some systems, raise the limit. We should really remove the
hard coded limit but this is needed as a fix so let's do the simple thing
and raise the limit for now.
