drm/amdgpu: Rename misspelled function

Instead of fixing the spelling in
  amdgpu_ras_eeprom_process_recods(),
rename it to,
  amdgpu_ras_eeprom_xfer(),
to look similar to other I2C and protocol
transfer (read/write) functions.

Also to keep the column span to within reason by
using a shorter name.

Change the "num" function parameter from "int" to
"const u32" since it is the number of items
(records) to xfer, i.e. their count, which cannot
be a negative number.

Also swap the order of parameters, keeping the
pointer to records and their number next to each
other, while the direction now becomes the last
parameter.
