New port support.

Hardware specification

STM32H7R/STM32H7S

Is your feature request related to a problem?

While TinyUSB already supports the H7 series, it uses an off-chip PHY over ULPI for the HS port. The H7RS series has a dedicated on-chip HS PHY, making it similar to the U5 series. The H7RS series is also distinct from the remaining H7 series, with different pin ports, and they even have their own separate HAL file, "stm32h7rsxx_hal.h".

Describe the solution you'd like

Support for STM32H7RS series if possible.

Based on the reference manual (RM0477, 3791 pages long), the OTG_FS FIFO has 1.25 Kbytes of dedicated RAM, while the OTG_HS FIFO has 4 Kbytes of dedicated RAM. Use "find in page" and search for "The USB system features" to find this.
