platform/olpc: olpc-xo175-ec: Use SPI device ID data to bind device

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.
