USB: musb: fix init oops crash with static FIFO config
Correct musb_read_fifosize() and musb_configure_ep0() functions
for the #ifndef BLACKFIN branch when the silicon uses static FIFO
configuration. (Most current silicon configures this controller
to use dynamic FIFO configuration; some parts from ST don't, like
the STM STA2062.)
