Subject: ARM: dts: at91: sama5d3 Xplained: don't disable hsmci regulator

From: Ludovic Desroches <[email protected]>

commit ae3fc8ea08e405682f1fa959f94b6e4126afbc1b 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.

Fixes 1b53e3416dd0 ("ARM: at91/dt: sama5d3 xplained: add fixed regulator for vmmc0")
