The zynq_sdhci controller driver use CONFIG_ZYNQ_SDHCI_MAX_FREQ as base
clock frequency but this clock is not fixed and depends on the hardware
configuration. Additionally the value of CONFIG_ZYNQ_SDHCI_MAX_FREQ
doesn't match the real base clock frequency of SDIO_FREQ. Use the clock
framework to determine the frequency at run time.

The sdhci controller assumes that the base clock frequency is fully supported by
the peripheral and doesn't support hardware limitations. The Linux kernel
distinguishes between base clock (max_clk) of the host controller and maximum
frequency (f_max) of the card interface. Use the same differentiation and allow
the platform to constrain the peripheral interface.

These functions can be much simpler by squashing lines for immediate
return.

For *_bind() callbacks, they will be a simple wrapper function of an
upper-level bind API.

For mmc_set_{boot_bus_width,part_conf}, they will be a wrapper of
mmc_switch().

We no longer need to set 'caps' as it's not passed to 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.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.
