[PATCH 1/2] ARM: davinci: board-da850-evm: Mark dcdc2 of TPS65070 as always_on

[Peter Ujfalusi]

DCDC2 should not be turned off since it is powering the CPU among other
things.

[PATCH 2/2] ARM: davinci: board-da850-evm: Add needed regulators for tlv320aic3106 codec

[Peter Ujfalusi]

IOVDD: tps65070's dcdc2
AVDD and DRVDD: fixed regulator derived from 5V via TPS73701DCQ
DVDD: fixed regulator derived from 5V via TPS73701DCQ

This patch needed to be able to probe the audio codec.

Applied both for v3.18 while fixing the following:

CHECK: Please use a blank line after function/struct/union/enum declarations
#56: FILE: arch/arm/mach-davinci/board-da850-evm.c:845:
