Subject: [PATCH 1/2] mmc: sdhci-uhs2: Fix calling incorrect sdhci_set_clock() function

From: Ben Chuang <ben.chuang@...esyslogic.com.tw>

Fix calling incorrect sdhci_set_clock() in __sdhci_uhs2_set_ios() when the
vendor defines its own sdhci_set_clock().

Fixes: 10c8298a052b ("mmc: sdhci-uhs2: add set_ios()")
Cc: stable@...r.kernel.org # v6.13+
