drivers/ipmi: Add uid parameter to struct drivers_ipmi_config

This change adds uid parameter to drivers_ipmi_config that can be used
by ipmi_ssdt() to store the uid value to be used by
ipmi_write_acpi_tables. This allows to remove the requirement in
ipmi_ssdt() to update dev->command. This is being done in preparation
to make the struct device * parameter to fill_ssdt as const.
