usb: musb: remove some register access wrapper functions

Browse Source 
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
