Input: rmi4 - fix register descriptor address calculation
When reading the register descriptor, the base address is incremented by
1 to read the presence register block. However, after reading the
presence register block, the address is incorrectly incremented by only
1 byte (++addr) instead of the actual size of the presence block
(size_presence_reg). This causes the subsequent structure block read to
read from the wrong memory location if the presence block is larger than
1 byte.
Fix this by advancing the address by size_presence_reg.
