doorbell_queue_map should always be allocated or we will need to
add branches around all accesses.

Force all the GPUs to a certain type, use the below command:
HSA_FORCE_ASIC_TYPE="10.1.0 1 gfx1010 14"
meaning major.minor.step dgpu asic_name asic_id
This will faciliate the cooperation across the teams for bringing up
ASICs which reuse existing device IDs.

Those tests are actually did not function up to its expectation because
some underlying functions such as suspend/resume and disable/enable KFD
were not implemented. Those interfaces would never be implemented, so
delete them.

The memory size alignment workaround for a TLB bug on gfx802 was
breaking userptrs because it would attempt to get_user_pages beyond
the end of a VMA. Refine this workaround based on our understanding
of the HW bug. It only affects L2 cacheline allocation, which is
decided by the last page in the cache line (8 entries = 32KB of
address space). Thus aligning memory allocation so that the last
page falls on the end of a 8 entry TLB cache line allows caching
to work correctly.
Imported images require specific alignments. If their size is not
naturally aligned with 8 cache lines, it may have bad TLB cache
performance.
This patch will only have the desired effect if redundant size
padding in KFD is also removed.

sdma end ts must be 256 bit aligned in oss 3.0 and prior. Using
the ts pool requires copying into the signal and is a significant
performance penalty for small copies.
SharedSignal is 128 bytes due to alignment so can host the end ts.
Move sdma end ts into SharedSignal and remove ts pool and ts copy.

hsakmt-dev should not install include/linux/* (currently just kfd_ioctl.h)
as those are linux kernel headers provided by the linux kernel header
packages (`linux-headers-*` on Debian/Ubuntu or `kernel-headers-*` on
Red Hat / Fedora)
