mediatek:adjust usb20 pull-up flow

Problem:
USB function will switch back to "Chagring only"
from MTP automatically on some PC, and this was
caused by UsbDeviceManager can't get USB connect
event on time.If response time is more than 1 sec,
UsbDeviceMange will switch to default "Chagring only".

Solution:
Don't do USB power on/off flow when cable already connected with PC.
Only need to set/clean MUSB_POWER_SOFT_CONN bit to speed-up PC re-enumeration.
