Subject: [PATCH] dre: Setup sim restart shell script

sm8450 and above have a very annoying SMS receiving bug where for some
carriers it won't work after a device restart if QTI telephony injection
isn't available, but one of the workarounds is to either use airplane
mode toggle or eject the sim card and reinsert it

Instead of doing that? Let's try and automate disabling and enabling the
sim card

EDIT: Some holi/blair devices have this problem too.
