i3c: dw: drop of_match_ptr for ID table

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here). This
also fixes !CONFIG_OF error:

drivers/i3c/master/dw-i3c-master.c:1201:34: error: ‘dw_i3c_master_of_match’ defined but not used [-Werror=unused-const-variable=]
