mfd: kempld: Fix kernel-doc struct member names

Correct the struct member names to avoid kernel-doc warnings:

Warning: include/linux/mfd/kempld.h:114 struct member 'gpio_base' not
 described in 'kempld_platform_data'
Warning: include/linux/mfd/kempld.h:114 struct member 'get_hardware_mutex'
 not described in 'kempld_platform_data'
Warning: include/linux/mfd/kempld.h:114 struct member
 'release_hardware_mutex' not described in 'kempld_platform_data'
