Add a PCI front-end to esp(4) allowing it to support AMD Am53C974 and replace amd(4) with the former in the amd64, i386 and pc98 GENERIC kernel configuration files. Besides duplicating functionality, amd(4), which previously also supported the AMD Am53C974, unlike esp(4) is no longer maintained and has accumulated enough bit rot over time to always cause a panic during boot as long as at least one target is attached to it (see PR 124667).

- Use device_t rather than the NetBSDish struct device. - Move esp_devclass to ncr53c9x.c in order to allow different bus front-ends to use it. - Use KOBJMETHOD_END. - Remove the gl_clear_latched_intr hook as it's not needed for any of the chips nor the front-ends supported in FreeBSD and likely never will be. - Correct the DMA constraints and only limit the tag used for the transfer buffers to 32-bit DMA as that address is written into a 32-bit register. - The ESP200 also only supports up to 64k transfers. - Don't let the DMA and SBus front-end supply a maximum transfer size larger than MAXPHYS as that's the maximum the upper layers use and we otherwise just waste resources unnecessarily. - Initialize the ECB callout and don't zero the handle when returning ECBs to the free list so that ncr53c9x_callout() actually is called with the driver lock held. - On detach the driver lock should be held across cam_sim_free() according to isp(4) and a panic received. - Check the return value of NCRDMA_SETUP(), i.e. bus_dmamap_load(9), and try to handle failures gracefully. - In ncr53c9x_action() replace N calls to xpt_done() in a switch with just one at the end. - On XPT_PATH_INQ report "NCR" rather than "Sun" as the vendor as the former is somewhat more correct as well as the maximum supported transfer size via maxio in order to take advantage of controllers that that can handle more than DFLTPHYS. - Freeze the device queue if a request didn't complete without error and isn't already frozen. - Print the number of MESSAGE (EXTENDED) rejected. - Fix the path encoded in the multiple inclusion protection of ncr53c9xvar.h. - Correct the DMA constraints used in the LSI64854 core to not exceed the maximum supported transfer size and include the boundary so we don't need to check on every setup of a DMA transfer. - Let the bus DMA map callbacks do nothing in case of an error. - Correctly handle > 64k transfers for FAS366 in the LSI64854. A new feature flag NCR_F_LARGEXFER was introduced so we just need to check for this one and not for individual controllers supporting large transfers in several places. - Let the LSI64854 core load transfer buffers using BUS_DMA_NOWAIT as the NCR53C9x core can't handle EINPROGRESS. Due to lack of bounce buffers support, sparc64 doesn't actually use EINPROGRESS and likely never will, as an example for writing additional front-ends for the NCR53C9x core it makes sense to set BUS_DMA_NOWAIT anyway though. - Some minor cleanup.

Adapt the locking of esp(4) to MPSAFE cam(4) (so that ncr53c9x_intr() actually is INTR_MPSAFE now) and fix a couple of bugs which lead to panics, amongst other improvements. Approved by: re (kib)
