ASoC: SOF: Intel: hda: Add flag to indicate that the firmware is IMR booted
Dynamic loading of external libraries should not be done if the firmware
was booted from IMR since in that case the libraries will be restored along
with the basefw.
The booted_from_imr flag is introduced and set to true if the IMR boot was
successful and to false if cold booting is executed.
The reason for the new flag is that guessing from existing flags, used to
decide if we should try booting from IMR or not is not going to be robust
as the IMR boot itself can fail and in that case a full, cold boot is
executed.
