broadcom/cygnus: Enable gpio on romstage
BUG=chrome-os-partner:35936
BRANCH=broadcom-firmware
TEST=When enable configuration CYGNUS_GPIO_TEST,
print on console:
Start gpio test...
[gpio_crmu] gpio:0 set input
[gpio_crmu] gpio:0 set pullup:0
GPIO get 170=0
gpio request enable pin=64 offset=0x1c
....
GPIO set 69=1
[gpio_asiu] gpio:45 set, value:0
GPIO set 69=0
Gpio test completed...
Additional test:
Measure on GPIO 69 to confirm the voltage
change.
Apply voltage on AON_GPIO0 to check reading.
