ipq40xx: 5.15: add patch commenting unused sdhci function

Browse Source 
Add patch commenting unused sdhci function, hopin this will be dropped
when the problem is actually found.
Fix compilation warning:
drivers/mmc/host/sdhci-msm.c:1781:13: error: 'sdhci_msm_set_clock' defined but not used [-Werror=unused-function]
 1781 | static void sdhci_msm_set_clock(struct sdhci_host *host, unsigned int clock)
      |             ^~~~~~~~~~~~~~~~~~~

Subject: [PATCH] mmc: sdhci-msm: comment unused sdhci_msm_set_clock
comment unused sdhci_msm_set_clock and __sdhci_msm_set_clock as due to some
current problem, we are forced to use sdhci_set_clock.
