[PATCH] regulator: ab8500: Remove stale expand_register kernel-doc entry

[Babanpreet Singh]

Commit aeee55b76bfd ("regulator: ab8500: Remove unused embedded struct
expand_register") deleted the expand_register member from struct
ab8500_regulator_info and, in the same hunk, added an empty
"@expand_register:" line to the kernel-doc block. That traded one W=1
warning for another:

  drivers/regulator/ab8500.c:196 Excess struct member 'expand_register'
  description in 'ab8500_regulator_info'

Drop the leftover line; the remaining @member entries all match the
struct.

No functional changes.
