arm64: dts: exynos5433: add sleep state for BCM4773 sensorhub gpios
The BCM4773 power pins need to be alive during sleep mode,
because the MCU needs to respond to the external sensors events.
Add a sleep alive state for pins.
- gpd2-0 (GPS_HUB_EN)
- gpf2-2 (MCU_AP_INT_2_1.8V)
- gpf2-3 (AP_MCU_INT_1.8V)
While pins:
- gpd8-0 (SHUB_SPI_SCK)
- gpd8-1 (SHUB_SPI_SSN)
- gpd6-0 (SHUB_SPI_MISO)
- gpd6-1 (SHUB_SPI_MOSI)
need to be managed when the device goes and resumes from
sleep mode.
