Hogander, Jouni May 29, 2024, 9:38 a.m. UTC 
We want to have sink Early Transport capability and usage in our psr
debugfs status interface.

v4: use su_region_et_enabled instead of psr2_su_region_et_valid
v3: remove extra space from "PSR mode:  disabled"
v2: printout "Selective Update enabled (Early Transport)" instead of
    "Selective Update Early Transport enabled"
