[U-Boot] [PATCH v2 2/2] mmc: sdhci: remove the unnecessary arguments for sdhci_setup_cfg

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.
