Fixes the following sparse warning:

drivers/mmc/host/sdhci_am654.c:161:18: warning:
 symbol 'sdhci_am654_ops' was not declared. Should it be static?

41fd4caeb0 mmc: sdhci_am654: Add Initial Support for AM654 SDHCI driver
The host controllers on TI's AM654 SOCs are not compatible with
the phy and consumer model of the sdhci-of-arasan driver. It turns out
that for optimal operation at higher speeds, a special tuning procedure
needs to be implemented which involves configuration of platform
specific phy registers.

Therefore, branch out to a new sdhci_am654 driver and add the phy
register space with all phy configurations to it. Populate AM654
specific callbacks to sdhci_ops and add SDHCI_QUIRKS wherever
applicable.

Only add support for upto High Speed for SD card and upto DDR52 speed
mode for eMMC. Higher speeds will be added in subsequent patches.
