usb: Modify sdp enumeration timeout value in charger mode
Write to /sys/class/typec/port<...>/device/update_sdp_enum_timeout
to reduce SDP enumeration timeout value when device is in charger
mode. This will enable faster detection of a DCP port.
ported from 6710e31a629f81cf308e1099f75a01c82db6d006
Test: Validate (in charger mode) that the sysfs attribute is 1
(meaning lower sdp timeout value is being used). Read dmesg to
see print showing timeout value is 5000ms.
