extcon: sm5502: Drop invalid register write in sm5502_reg_data

stable inclusion

commit e16fcc83748a25107dd2deb047b1db2aa6420fdf
bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY

--------------------------------

[ Upstream commit d25b224f ]

When sm5502_init_dev_type() iterates over sm5502_reg_data to
initialize the registers it is limited by ARRAY_SIZE(sm5502_reg_data).
There is no need to add another empty element to sm5502_reg_data.

Having the additional empty element in sm5502_reg_data will just
result in writing 0xff to register 0x00, which does not really
make sense.
