BugLink: https://bugs.launchpad.net/bugs/2072786 SRU Justification: [Impact] This is an enhancement to enable the hw_reset() support in the sdhci-of-dwcmshc driver for BlueField-3. [Fix] BLueField eMMC RST_N register is implemented as secure, thus the default hw_reset() implementation won't work. This patch provides BlueField specific hw_reset() which send SMC call to ATF to update the same RST_N register. [Test Case] Same functionality and testing as on BlueField-3. [Regression Potential] Same behavior from user perspective.
