drm/amdgpu: Report ras_num_recs in debugfs

Browse Source 
Report the number of records stored in the RAS EEPROM table in debugfs.

This can be used by user-space to calculate the capacity of the RAS EEPROM
table since "bad_page_cnt_threshold" is also reported in the same place in
debugfs.

See commit 7fb6407145 ("drm/amdgpu: Add bad_page_cnt_threshold to debugfs").

ras_num_recs can already be inferred by dumping the RAS EEPROM table, also in
the same debugfs location, see commit reference c65b0805e7 (drm/amdgpu:
RAS EEPROM table is now in debugfs, 2021-04-08). This commit makes it an
integer value easily shown in a single file.
