[Anson Huang]

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
(5fe156f 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
