[PATCH] mmc: zynq_sdhci: Add weak function prototype

[Michal Simek]

From: T Karthik Reddy <t.karthik.reddy at xilinx.com>

zynqmp_pm_is_function_supported() which checks feature support on som,
which is implemented in firmware_zynqmp.c driver. As mini configuration
does not use firmware driver, so create a weak function to avoid
compilation error on zynqmp mini configuration.
