DRA7 evm REV G and later boards uses a vtt regulator for DDR3 termination and this is controlled by gpio7_11. This gpio is configured in boot loader. gpio7_11, which is only available only on Pad A22, in previous boards, is connected only to an unused pad on expansion connector EXP_P3 and is safe to be muxed as GPIO on all DRA7-evm versions (without a need to spin off another dts file). Since gpio7_11 is used to control VTT and should not be reset or kept in idle state during boot up else VTT will be disconnected and DDR gets corrupted. So, as part of this change, mark gpio7 as no-reset and no-idle on init.
