[PATCH v2] platform: olpc: use SPI device ID data to bind device

[PATCH v2] platform: olpc: use SPI device ID data to bind device

[Krzysztof Kozlowski]

The driver defines spi_device_id table for module autoloading, but does
not use it in id_table which causes W=1 warning:

  drivers/platform/olpc/olpc-xo175-ec.c:737:35: error: ‘olpc_xo175_ec_id_table’ defined but not used [-Werror=unused-const-variable=]

Reference the SPI device ID table, so it can be also used for device
binding.

Changes since v1:
1. Rework the patch - reference the ID table instead of __maybe_unused.

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
