These were all bogus, since the actual problem here is the incorrect use of of_ptr(). Since the driver (like any other modern platform driver) only works in combination with CONFIG_OF, there is no point in hiding the reference, so just remove that along with all the pointless #ifdef checks in the driver. This improves build coverage and avoids running into the same problem again when another part of the driver gets changed that relies on the #ifdef blocks to be completely matched.

There is sometimes a need to intentionally pick the relaxed accessor for performance critical functions, but I noticed that each hantro_reg_write() call also contains a non-relaxed readl(), which is typically much more expensive than a writel, so there is little benefit here but an added risk of missing a serialization against DMA. To make this behave like other interfaces, use the normal accessor by default and only provide the relaxed version as an alternative for performance critical code. hantro_postproc.c is the only place that used both the relaxed and normal writel, but this does not seem cricital either, so change it all to the normal ones.
