add hpmicro chips and hpm6750evk2 board

[HiFiPhile]

Hi, think you, I think HP Micro use Chipidea HS controller, could you add the port to /src/portable/chipidea/ci_hs instead of creating a new ?

Yes, I update my port files by using Chipidea HS controller to support HPMicro chips. Thank you!

Pull request overview

This PR adds support for HPMicro chips (specifically HPM6750) and the hpm6750evk2 development board to TinyUSB. The implementation includes BSP files, USB driver integration with ChipIdea HS controller, and RISC-V toolchain updates.

Key changes:

• Integration of HPM6750 MCU with ChipIdea HS USB controller and EHCI support
• Complete BSP implementation for hpm6750evk2 board with dual USB port support
• RISC-V toolchain update to include zifencei extension for GCC compatibility

The change from assignment (=) to bitwise OR (|=) modifies the behavior for all MCUs, not just HPM. This could potentially preserve unwanted bits that were previously cleared. If this change is necessary for HPM compatibility, consider making it conditional with #if TU_CHECK_MCU(OPT_MCU_HPM) or document why this change is safe for all supported MCUs.

Suggested change

	dcd_reg->PORTSC1 |= PORTSC1_FORCE_FULL_SPEED;
	#if TU_CHECK_MCU(OPT_MCU_HPM)
	dcd_reg->PORTSC1 |= PORTSC1_FORCE_FULL_SPEED;
	#else
	dcd_reg->PORTSC1 = PORTSC1_FORCE_FULL_SPEED;
	#endif

Typo in the family name. "HPMIRCO" should be "HPMICRO".

Suggested change

	set(FAMILY_MCUS HPMIRCO CACHE INTERNAL "")
	set(FAMILY_MCUS HPMICRO CACHE INTERNAL "")
