This patch adds the compatible string in sdhci-of-arasan.c to
support sdhci-arasan5.1 version of controller. No documented
controller IP version is found in the TRM, so we use ths version
of command queueing engine integrated into this controller by arasan
to specify our controller.

Changes in v1:
- Remove redundant SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN for "arasan, sdhci-5.1" since
SDHCI will check "host->max_clk == 0" and let driver get it from host->ops->get_max_clock.
