USB EP0 reads data from the fifo but doesn't mark the read
done which adds significant delays. Fix this unnecessary
slowdown due to operation timeouts by finishing the read
properly.
Also add a missing function description to the function
mpfs_ep_set_fifo_size().

Move the target specific memory map to a separate file so there is no
need to copy&paste the __xxram_start etc linker symbols to each file
that needs them.
Also add MMU flags for I/O and kernel areas, they will be needed
when the kernel runs with virtual addresses also.
Some fields of mstatus were marked as Reserved Writes Preserve Values, Reads Ignore Values (WPRI),
so we must keep its origin value with addition flags.

Also fix data reads that provide garbage for the first request.
It has always random data as it's completed prior to any read
operation.

This adds a simple USB device driver for the mpfs. However,
this driver is still at its early phase. Only limited testing
with CDC/ACM has been conducted.
