From: Jules Maselbas <jmaselbas@kalray.eu>

The phy utmi width information is already set in hsotg params,
phyif is only used in few places and I don't see any reason to
not use hsotg's params.

Moreover the utmi width was being forced to 16 bits by platform
initialization which doesn't take in account HW configuration.

Fix indentation and remove unneeded space after 'return' keyword.  This
fixes checkpatch warning:
    WARNING: Statements should start on a tabstop

Applied both in the series and ignore the (3rd?) usb patch! thanks
