media: venus: core: Add io base variables for each block
[ Upstream commit b4053a2097ec2f8ea622e817ae5a46a83b23aefe ]
New silicon means that the pre-determined offsets we have been using
in this driver no longer hold. Existing blocks of registers can exist at
different offsets relative to the IO base address.
This commit adds a routine to assign the IO base hooks a subsequent commit
will convert from absolute to relative addressing.
