usb: musb: Don't set d+ high before enable for 2430 glue layer
At least 2430 glue layer pulls d+ high on start up even if there are
no gadgets configured. This is bad at least for anything using a separate
battery charger chip as it can confuse the charger detection.
Let's fix the issue by removing the bogus glue layer code tinkering
with the SESSION bit. As pointed out Bin Liu <[email protected]> and
Sergei Shtylyov <[email protected]>, the SESSION
bit just starts host mode if ID pin is grounded, and starts the
srp is ID pin is floating. So without the ID pin changing, it's
unable to force musb mode to anything. And just for starting a
host mode, things work fine without this code.
