acpi: Make acpi_device_write_dsd_gpio() public
Make sure it can be used for other driver.
At present, i2c_generic_write_gpio() is not suitable for being called
by other drivers, so delete it, add acpi_device_write_dsd_gpio() to
replace it, and make it public.
BUG=None
TEST= Build BIOS FW pass and it can be use for other driver.
