SMPS10 supports different modes such as BOOST mode, BYPASS mode and
SWITCH. Inorder to configure SMPS10 in these modes,
added palmas_set_mode_smps10() and palmas_get_mode_smps10() for the
consumers of SMPS10 to configure it accordingly.

Only compile tested. Just sent a patch to get some comments
/ideas on how to handle such one off regulators.
