arm: tegra: cardhu: Configuring DEV_SLP and gpio2 for A04
Configuring the tps6591x into DEV_SLP mode and
gpio2 of tps6591x into sleep mode for E1291-A04 board.
This is required in order to have the gpio2 follow the
'CORE_PWR_REQ' pin in E1291-A04. GPIO2 of tps6591x is
connected to the EN of the DC-DC converter which supply
core voltage.
