[U-Boot] [PATCH 2/2] mmc: sdhci: remove the unnecessary argumetns for sdhci_setup_cfg

[Jaehoon Chung]

Some arguments don't need to pass to sdhci_setup_cfg.
Generic variable can be used in sdhci_setup_cfg, and some arguments are
already included in sdhci_host struct.

It's enough that just pass the board specific things to sdhci_setup_cfg().
After removing the unnecessary arguments, it's more simpler than before.
It doesn't consider "Version" and "Capabilities" anymore in each SoC
driver.

If applied my patches, then i want to apply this at first, not "s5p_sdhci: support the Driver model for Exynos".
But I want to know Simon's opinion about this patch. I don't know correct why passed the buswidth.

The below patch will resend with other patch..(Modify Device-tree and remove the unused codes.)

Are you going to pick this up? I suggest that it goes in now since it
will affect people porting drivers.

I think it's related with DM side. So if you can pick this, I'm ok.
Otherwise, i will apply on u-boot-mmc, today..And tomorrow i will request pull.

Ok, I will do. And tomorrow, I will request pull to Tom for u-boot-mmc with other mmc patches.
How about?
