pmic: Extend PMIC framework to support multiple instances of PMIC devices
The PMIC framework has been extended to support multiple instances of the variety of devices responsible for power management. This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB Interface Circuit). Power related includes have been moved to ./include/power directory. This is a first of a series of patches - in the future "pmic" will be replaced with "power". Two important issues: 1. The PMIC needs to be initialized just after malloc is configured 2. It uses list to hold information about available PMIC devices Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Stefano Babic <sbabic@denx.de>
