Neil Armstrong	0789724f86	firmware: meson_sm: Add serial number sysfs entry ...

The serial number is simply exposed as a sysfs entry under the firmware sysfs directory.

Carlo Caione	83e007a0c6	firmware: meson-sm: Check for buffer output size ... After the data is read by the secure monitor driver it is being copied in the output buffer checking only the size of the bounce buffer but not the size of the output buffer. Fix this in the secure monitor driver slightly changing the API. Fix also the efuse driver that it is the only driver using this API to not break bisectability.
