usb: dwc2/gadget: assign TX FIFO dynamically

Because we have not enough memory to have each TX FIFO of size at least
3072 bytes (the maximum single packet size with 3 transactions per
microframe), we create four FIFOs of lenght 1024, and four of length
3072 bytes, and assing them to endpoints dynamically according to
maxpacket size value of given endpoint.

Up to now there were initialized 16 TX FIFOs, but we use only 8 IN
endpoints, so we can split available memory for 8 FIFOs to have more
memory for each one.

It needed to do some small modifications in few places in code, because
there was assumption that TX FIFO numbers assigned to endpoints are the
same as the endpoint numbers, which is not true since we have dynamic
FIFO assigning.

usb: dwc2: clip max_transfer_size to 65535

Clip max_transfer_size to 65535 for host. dwc2_hc_setup_align_buf()
allocates coherent buffers with this size, and if it's too large we
can exhaust the coherent DMA pool.

usb: dwc2: handle DMA buffer unmapping sanely

The driver's handling of DMA buffers for non-aligned transfers
was kind of nuts. For IN transfers, it left the URB DMA buffer
mapped until the transfer completed, then synced it, copied the
data from the bounce buffer, then synced it again.

Instead of that, just call usb_hcd_unmap_urb_for_dma() to unmap
the buffer before starting the transfer. Then no syncing is
required when doing the copy. This should also allow handling of
other types of mappings besides just dma_map_single() ones.

Also reduce the size of the bounce buffer allocation for Isoc
endpoints to 3K, since that's the largest possible transfer size.

Tested on Raspberry Pi and Altera SOCFPGA.
