Subject: [PATCH 4.4 192/210] ARM: dts: at91: sama5d4 Xplained: dont disable hsmci regulator

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ludovic Desroches <ludovic.desroches@...el.com>

commit b02acd4e62602a6ab307da84388a16bf60106c48 upstream.

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