[PATCH 04/10] mmc: omap: fix mmc_omap_report_irq to use dev_dbg macros

[Venkatraman S <svenkatr@ti.com>]

The function mmc_omap_report_irq uses raw printks and the
actual output was disabled by a static variable. Make
the function use dev_vdbg macro and use it under the
standard CONFIG_MMC_DEBUG flag.
