mfd: Add support for RICOH PMIC RC5T583
Ricoh power management IC RC5T583 contains is multi functional device having multiple sub devices inside this. This device has multiple dcdc/ldo regulators, gpios, interrupt controllers, on-key, RTCs, ADCs. This device have 4 DCDCs, 8 LDOs, 8 GPIOs, 6 ADCs, 3 RTCs etc. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>hifive-unleashed-5.1

This driver provides common support for accessing the device
