Truncate the 64bit base address from ip discovery and only store lower 32bit
ip base in reg_offset[].
Bits > 32 follows ASIC specific format, thus just discard them and handle it
within specific ASIC.
By this way reg_offset[] and related helpers can stay unchanged.

Four basic reasons as below to do the change:
1. number of ring expand a lot on aqua_vanjaram, and adjustment on old
assignment cannot make each ring in a continuous doorbell space.
2. the SDMA doorbell index should not exceed 0x1FF on aqua_vanjaram due to
regDOORBELLx_CTRL_ENTRY.BIF_DOORBELLx_RANGE_OFFSET_ENTRY field width.
3. re-design the doorbell assignment and unify the calculation as
"start + ring/inst id" will make the code much concise.
