spi: efm32: properly namespace location property
While reviewing an i2c driver for efm32 that needs a similar property Wolfram Sang pointed out that "location" is a too generic name for something that is efm32 specific. So add an appropriate namespace and fall back to the generic name in case of failure. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
