[PATCH] mmc: dwcmshc_bf3_hw_reset: Log eMMC reset calls

[Satyansh Shukla]

Log when the BlueField-3 eMMC hardware reset path is invoked and
whether the RST_N SMC call succeeds.

This makes it easier to diagnose cases where the controller recovery path
depends on issuing an eMMC reset, and helps confirm that the reset sequence
was attempted on affected systems.
