Subject: [PATCH] ARM: at91/dt: sama5d4 xplained: don't disable hsmci regulator

If enabling the hsmci regulator on card detection, the board can reboot
on sd card insertion. Keeping the regulator always enabled fixes this
issue.

And changed the $subject prefix to the new convention:
"ARM: dts: at91:"

Thanks, bye.
