Fix host rp2040 with low speed device

[hathach]

Describe the PR
Fix host rp2040 when mounting low speed device (e.g keyboard) with max packet size = 8

• Correct Data Toggle by number of packet: e.g 64 bytes = 8 x 8 bytes --> Data Toggle should not be flipped in the next buffer.
• Improve RP2040-E4 (host buf sel) fix to prevent panic with already available.

Fix #709, also replace raspberrypi/tinyusb#7 as the fix

not sure i you meant to leave all the extra logging stuff in there?

note i'd like to pull this into the pico-0.10.0 branch anyway which we'll ship SDK1.2.0 with most likely

no problem, I could release this as 0.10.1 , there is also issue when using pico reading msc thumbdrive as well. I will try to look at when I got time.

Looks good to me assuming @kilograham agrees the Low Speed DATA PID conversation is resolved.

The PID is toggled by hardware as captured in analyzer. without the fix, it will trigger the incorrect PID USB_INTS_ERROR_DATA_SEQ_BITS error. Thank for the review, I will merge this since I have another PR pending since yesterday.

ah, ok; "the code may be wrong, but fixes the problem at hand" :-) I'm cool with it for now!

The code is spot on afaik. Please provide example or hands on test case if you are still in doubt.

PS: you guys could check this with hw ip team. I could only test its behavior from the sw point of view
