ARM: dts: msm: designate LDO12 as a parent of LDO24 on sdm845 



On SDM845 there is a HW bug that could lead to chip damage if
the 3.1V rail (normally provided by PM8998 LDO24) is turned on
while the 1.8V (LDO12) rail is off. A simple workaround is to
ensure that LDO12 is turned on prior to LDO24. Achieve this by
making pm8998_l12 the parent-supply of the pm8998_l24 regulator.
