[PATCH 4.17 231/336] mmc: sdhci-omap: Fix when capabilities are obtained from SDHCI_CAPABILITIES reg

[Greg Kroah-Hartman]

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kishon Vijay Abraham I <kishon@xxxxxx>

[ Upstream commit 0ec4ee3c9b9755b28fd2e89b2ceaae6f15403368 ]

sdhci_omap_config_iodelay_pinctrl_state() requires caps and caps2 to be
initialized (speed mode capabilities like UHS/HS200) before it is
invoked. While mmc_of_parse() initializes caps/caps2 if capabilities is
populated in device tree, it will remain uninitialized for capabilities
obtained from SDHCI_CAPABILITIES register.
Fix sdhci_omap_config_iodelay_pinctrl_state() to be used even while
getting the capabilities from SDHCI_CAPABILITIES register by invoking
sdhci_setup_host() before sdhci_omap_config_iodelay_pinctrl_state().
