On i.MX6SLL EVK board, PFuze100's SW4 is supplying
LPDDR3, it needs to be always on. This patch fixes
Linux kernel boot up hang caused by commit 5fe156f1cab4
("regulator: pfuze100: add enable/disable for switch"),
because SW4 is turned off unexpectedly:
[ 1.693613] cfg80211: failed to load regulatory.db
[ 1.700063] SW4: disabling
[ 1.703973] SWBST: disabling
