Subject: [PATCH 4.9 42/68] ARM: dts: beagle-x15-common: Model 5V0 regulator

From: Kishon Vijay Abraham I <kishon@...com>

[ Upstream commit e17e7c498d4f734df93c300441e100818ed58168 ]

On am57xx-beagle-x15, 5V0 is connected to P16, P17, P18 and P19
connectors. On am57xx-evm, 5V0 regulator is used to get 3V6 regulator
which is connected to the COMQ port. Model 5V0 regulator here in order
for it to be used in am57xx-evm to model 3V6 regulator.
