Currently .get_max_clock returns the current clock rate for cclk_emmc on rk35xx, thus max clock gets set to whatever bootloader set it to. In case of u-boot, it is intentionally reset to 50 MHz if it boots from eMMC, see mmc_deinit() in u-boot sources. As a result, HS200 and HS400 modes are never selected by Linux, because dwcmshc_rk35xx_postinit clears appropriate caps if host->mmc->f_max is < 52MHz cclk_emmc is not a fixed clock on rk35xx, so using sdhci_pltfm_clk_get_max_clock is not appropriate here. Implement rk35xx_get_max_clock that returns actual max clock for cclk_emmc.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
