Subject: [PATCH v2 3/8] mfd: tps65218: Use mfd_add_devices instead of of_platform_populate

mfd_add_devices enables parsing device tree nodes without compatibles
for child nodes. Replace of_platform_populate with mfd_add_devices.
mfd_cell currently is populated with only regulators.

Signed-off-by: Keerthy <j-keerthy@...com>

Changes in v2:

  * Updated commit log.

As of now only regulators driver is in kernel. The PMIC contains
a bunch of GPIOs, Over temperature warning / shutdown unit.
