[PATCH] mmc: sdhci-brcmstb: Resolve "unused" warnings with CONFIG_OF=n

[PATCH] mmc: sdhci-brcmstb: Resolve "unused" warnings with CONFIG_OF=n

[Brian Norris]

With W=1, we can see this gcc warning:

drivers/mmc/host/sdhci-brcmstb.c:182:34: warning: ‘sdhci_brcm_of_match’ defined but not used [-Wunused-const-variable=]
  182 | static const struct of_device_id sdhci_brcm_of_match[] = {
      |                                  ^~~~~~~~~~~~~~~~~~~

Rather than play around more with #ifdef's, the simplest solution is to
just mark this __maybe_unused.
