Tom St Denis 988f31ecc2 amdgpu: Unlock mutex if base_required is invalid
In the function amdgpu_vamgr_find_va() the function would return
without unlocking the mutex if the base_required offset was below
the va managers base offset.

Jammy Zhou 56d8dd6a9c amdgpu: make vamgr per device v2
Each device can have its own vamgr, so make it per device now.
This can fix the failure with multiple GPUs used in one single
process.

v2: rebase

Jammy Zhou ffa305d0fc amdgpu: add flag to support 32bit VA address v4
The AMDGPU_VA_RANGE_32_BIT flag is added to request VA range in the
32bit address space for amdgpu_va_range_alloc.

The 32bit address space is reserved at initialization time, and managed
with a separate VAMGR as part of the global VAMGR. And if no enough VA
space available in range above 4GB, this reserved range can be used as
fallback.

v2: add comment for AMDGPU_VA_RANGE_32_BIT, and add vamgr to va_range
v3: rebase to Emil's drm_private series
v4: fix one warning
