drm/amdgpu: dump RAS EEPROM table via debugfs

Browse source

When the RAS core manages the EEPROM, the eeprom_control is never
initialized (amdgpu_ras_init_badpage_info() returns early), so reading
ras/ras_eeprom_table in debugfs printed only a zeroed header and no
records, even though bad-page records exist in the RAS core EEPROM.

Source the table header and records from the RAS core EEPROM
(ras_core->ras_eeprom) in that case, reusing the existing output layout
so the debugfs node keeps the same format. Skip the dump when the
firmware manages the EEPROM, since the records are not stored in the
I2C-backed table then.
