mfd: intel_soc_pmic_*: Consistently use filename as driver name

Currently the intel_soc_pmic_bxtwc, intel_soc_pmic_chtwc and
intel_soc_pmic_crc PMIC drivers use more or less free form strings
for their driver name.

Where as intel_soc_pmic_chtdc_ti and intel_soc_pmic_mrfld use the driver's
filename as driver name.

Update the 3 others to also use the driver's filename to make the naming
consistent.
