[PATCH v4 5/6] mfd: tps65218: Use mfd_add_devices instead of of_platform_populate

[Keerthy]

mfd_add_devices enables parsing device tree nodes without compatibles
for regulators and gpio modules. Replace of_platform_populate with
mfd_add_devices. mfd_cell currently is populated with regulators,
gpio and powerbutton.

Changes in v4:

  * Regrouped the mfd cells better.
