octeontx2-af: Fix APR entry mapping based on APR_LMT_CFG

The current implementation maps the APR table using a fixed size,
which can lead to incorrect mapping when the number of PFs and VFs
varies.
This patch corrects the mapping by calculating the APR table
size dynamically based on the values configured in the
APR_LMT_CFG register, ensuring accurate representation
of APR entries in debugfs.
