There was no need to have prcm definitions for H6 and similar SoCs till now. However, support R_I2C will be needed soon in SPL.
Move old definitions to prcm_sun6i.h and add new ones in prcm_sun50i.h. One of those files will be selected in common prcm.h based on defined macros.
This commit doesn't do any functional change.
That looks alright. prcm.h and prcm_sun6i.h are identical, apart from the header guards. I could verify most of the sun50i PRCM fields by comparing to the Linux CCU_R driver, but not all of them. Out of curiosity, where do those offsets actually come from? Some BSP code? And they are actually SUN50I_H6 aka. "NCAT" specific, right?
Anyway, the interesting part (R_I2C clock gate offset) is correct, so:
