Subject: [PATCH v2 06/23] bus: mhi: Cleanup the register definitions used in headers
Cleanup includes:
1. Moving the MHI register definitions to common.h header with REG_ prefix
and using them in the host/internal.h file as an alias. This makes it
possible to reuse the register definitions in EP stack that differs by
a fixed offset.
2. Using the GENMASK macro for masks
3. Removing brackets for single values
4. Using lowercase for hex values
5. Using two digits for hex values where applicable
