Superb !!! Thank you very much for the PR, it looks great. I haven't tested it on hardware (will do later on), I only have a couples of feedback per review. Let's me know if you think otherwise.

it is a great idea, hopefully after a few round of enhancement like this pr, we could have a great FIFO allocation scheme. |

Describe the PR
Implementation of #540.
TX FIFOs are now starting to allocate from the top, RX FIFO at the bottom of the available space (like heap and stack). As such, free space is between TX and RX allocations allowing the RX FIFO to grow in size dynamically which is needed in case an ISO OUT EP is opened which is greater than the standard RX FIFO size. Also, once such an OUT EP is closed, the RX FIFO size will be reduced once the RX FIFO is empty.
