acpi: Call acpi_gen_writeSTA by status from device tree
The device tree now supports 'hidden' and the status can be found in
`struct device.hidden`. A new acpi_device_status() will return the
expected setting of STA from a `struct device`.
BUG=b:72200466
BRANCH=eve
TEST=Builds and boots properly on device eve
