Subject: [PATCH V10 6/9] mfd: pm8008: Add mfd_cell struct to register LDOs

Add mfd_cell struct to probe LDO regulators using
devm_mfd_add_devices() API.

Signed-off-by: Satya Priya <quic_c_skakit@...cinc.com>
---
Changes in V8:
 - Split the probe for infra and regulator devices
 - Add the reset-gpio toggling in the infra driver probe

Changes in V9:
 - Fixed nits.

Changes in V10:
 - Removed the extra probe added for regulators as is is not needed now.
