[PATCH v2 resend 1/2] gpio: tps68470: Fix tps68470_gpio_get() reading from the wrong register

[Hans de Goede <hdegoede@redhat.com>]

For the regular GPIO pins the value should be read from TPS68470_REG_GPDI,
so that the actual value of the pin is read, rather than the value the pin
would output when put in output mode.
