[PATCH v2 2/2] extcon: max8997: add missing const

[Jingoo Han <jg1.han@samsung.com>]

Fixed the checkpatch warning as below:

  WARNING: static const char * array should probably be static const char * const
  #163: FILE: drivers/extcon/extcon-max8997.c:163:
  +static const char *max8997_extcon_cable[] = {

Also, const is added to variable 'supported_cable' to prevent
build warning as below:

  drivers/extcon/extcon-max8997.c: In function 'max8997_muic_probe':
  drivers/extcon/extcon-max8997.c:708:30: warning: assignment discards 'const' qualifier from pointer target type [enabled by
default]

Changes since v1:
- Added const to variable 'supported_cable'
