usb: musb: remove some register access wrapper functions

The following wrappers were defined because of Blackfin support. Now
Blackfin support is removed, these wrappers are no longer needed, so
remove them.

musb_write_txfifosz
musb_write_txfifoadd
musb_write_rxfifosz
musb_write_rxfifoadd
musb_write_ulpi_buscontrol
musb_read_txfifosz
musb_read_txfifoadd
musb_read_rxfifosz
musb_read_rxfifoadd
musb_read_ulpi_buscontrol
musb_read_hwvers
