557c03157c mmc: sdhci-milbeaut: Remove redundant platform_get_irq error message 
platform_get_irq() will call dev_err() itself on failure,
so there is no need for the driver to also do this.
This is detected by coccinelle.

dd79b7e367 mmc: sdhci-milbeaut: add Milbeaut SD controller driver 
SD Host controller on Milbeaut consists of two controller parts.
One is core controller F_SDH30, this is similar to sdhci-fujitsu
controller.
Another is bridge controller.
This bridge controller is not compatible with sdhci-fujitsu controller.
This is special for Milbeaut series. This has some functions.
For example, reset control, clock enable/select for SDR50/25/12, set
property of SD physical pins, retuning control, set capabilityies.

This bridge controller requires special procedures at reset or clock
enablement or change for further tuning of clock.
