Currently setting enable_psr kernel parameter to != -1 is disabling
Panel Replay and Early Transport. This patch set is changing
enable_psr meaning as follows:

-1 = PSR1 : yes, PSR2 = yes, Panel Replay : yes
 0 = PSR1 : no,  PSR2 = no,  Panel Replay : no
 1 = PSR1 : yes, PSR2 = no,  Panel Replay : yes
 2 = PSR1 : yes, PSR2 = yes, Panel Replay : no

I.e. 1 disables PSR2 and 2 disables Panel replay. 0 disables PSR/Panel
Replay completely. Enable_psr parameter doesn't impact Early Transport
anymore.
