mfd: intel_soc_pmic_chtdc_ti: Set use_single_read regmap_config flag

Browse Source 
Testing has shown that reading multiple registers at once (for 10-bit
ADC values) does not work. Set the use_single_read regmap_config flag
to make regmap split these for us.

This should fix temperature opregion accesses done by
drivers/acpi/pmic/intel_pmic_chtdc_ti.c and is also necessary for
the upcoming drivers for the ADC and battery MFD cells.
