power: smb5-lib: Report the CURRENT_MAX as 1A in CC-mode

Browse source 
Userspace uses the CURRENT_MAX power-supply property to
determine the strength of the charger. In CC-mode of operation
the main-charger's ICL is configured low and hence the
CURRENT_MAX reported is lower attributing it as a weak-charger.
Fix this by reporting a fixed value of 1A during CC-mode.
