The device tree node for SoCFPGA's MMC device has the `resets =` property,
but is missing the `reset-names = "reset";` property. This causes the
"dw_mmc" driver to output a warning:
WARNING: dw_mmc ff704000.dwmmc0@xxxxxxxxxxx: error claiming reset: Invalid argument
Add the missing `reset-names` property to the `&mmc` node in
"arch/arm/dts/socfpga.dtsi". It probably needs fixing in the upstream
Linux device tree sources too!

v2: Updated commit message because it no longer fails to initialize the
MMC device since commit 724512bbac14 ("mci: dw_mmc: make reset control
optional again").
