drm/amdkfd: get doorbell's absolute offset based on the db_size
[ Upstream commit 367a0af43373d4f791cc8b466a659ecf5aa52377 ]
Here, Adding db_size in byte to find the doorbell's
absolute offset for both 32-bit and 64-bit doorbell sizes.
So that doorbell offset will be aligned based on the doorbell
size.
v2:
- Addressed the review comment from Felix.
v3:
- Adding doorbell_size as parameter to get db absolute offset.
v4:
Squash the two patches into one.
