All throughout the driver, normal kernel pointers are
stored as 'u64' struct members, which is kind of silly
and requires casting through a uintptr_t to void* every
time they are used.
There is one line that missed the intermediate uintptr_t
case, which leads to a compiler warning:
drivers/misc/habanalabs/common/command_buffer.c: In function 'hl_cb_mmap':
drivers/misc/habanalabs/common/command_buffer.c:512:44: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
512 | rc = hdev->asic_funcs->cb_mmap(hdev, vma, (void *) cb->kernel_address,
Rather than adding one more cast, just fix the type and
remove all the other casts.
Fixes: 0db575350c ("habanalabs: make use of dma_mmap_coherent")

ArmCP mandates that the device CPU is always an ARM processor, which might
be wrong in the future.
Most of this change is an internal renaming of variables, functions and
defines but there are two entries in sysfs which have armcp in their
names. Add identical cpucp entries but don't remove yet the armcp entries.
Those will be deprecated next year. Add the documentation about it in sysfs
documentation.

For internal needs of our CI we need to move all the common code into a
common folder instead of putting them in the root folder of the driver.
Same applies to the common header files under include/
