Add support for SPARC64 V (and where it already makes sense for other HAL/Fujitsu) CPUs. For the most part this consists of fleshing out the MMU and cache handling, it doesn't add pmap optimizations possible with these CPU, yet, though. With these changes FreeBSD runs stable on Fujitsu Siemens PRIMEPOWER 250 and likely also other models based on SPARC64 V like 450, 650 and 850. Thanks go to Michael Moll for providing access to a PRIMEPOWER 250.

- Assert that HEAPSZ is a multiple of PAGE_SIZE as at least the firmware of Sun Fire V1280 doesn't round up the size itself but instead lets claiming of non page-sized amounts of memory fail. - Change parameters and variables related to the TLB slots to unsigned which is more appropriate. - Search the whole OFW device tree instead of only the children of the root nexus device for the BSP as starting with UltraSPARC IV the 'cpu' nodes hang off of from 'cmp' (chip multi-threading processor) or 'core' or combinations thereof. Also in large UltraSPARC III based machines the 'cpu' nodes hang off of 'ssm' (scalable shared memory) nodes which group snooping-coherency domains together instead of directly from the nexus. - Add support for UltraSPARC IV and IV+ BSPs. Due to the fact that these are multi-core each CPU has two Fireplane config registers and thus the module/target ID has to be determined differently so the one specific to a certain core is used. Similarly, starting with UltraSPARC IV the individual cores use a different property in the OFW device tree to indicate the CPU/core ID as it no longer is in coincidence with the shared slot/socket ID. While at it additionally distinguish between CPUs with Fireplane and JBus interconnects as these also use slightly different sizes for the JBus/agent/module/target IDs. - Check the return value of init_heap(). This requires moving it after cons_probe() so we can panic when appropriate. This should be fine as the PowerPC OFW loader uses that order for quite some time now.

For cheetah-class CPUs ensure that the dt512_0 is set to hold 8k pages for all three contexts and configure the dt512_1 to hold 4MB pages for them (e.g. for direct mappings). This might allow for additional optimization by using the faulting page sizes provided by AA_DMMU_TAG_ACCESS_EXT for bypassing the page size walker for the dt512 in the superpage support code.

Add convenience macros for the bits in ASI_ESTATE_ERROR_EN_REG (used for ECC handling) and the additional uses of the ASIs 0x77 and 0x7f as well as their bits (used for a CPU bug workaround).

Flesh out the sparc64 port considerably. This contains: - mostly complete kernel pmap support, and tested but currently turned off userland pmap support - low level assembly language trap, context switching and support code - fully implemented atomic.h and supporting cpufunc.h - some support for kernel debugging with ddb - various header tweaks and filling out of machine dependent structures
