The RK818 PMIC contains a charger. Add very basic charger functionality to be able to regulate the USB input current and charger shutdown limits.

The phyCORE-RK3288 is a SoM (System on Module) containing a RK3288 SoC. The module can be connected to different carrier boards. It can be also equipped with different RAM, SPI flash and eMMC variants. The Rapid Development Kit option is using the following setup:

- 1 GB DDR3 RAM (2 Banks) - 1x 4 KB EEPROM - DP83867 Gigabit Ethernet PHY - 16 MB SPI Flash - 4 GB eMMC Flash

Add basic support for the PCM-947 carrier board, a RK3288 based development board made by PHYTEC. This board works in a combination with the phyCORE-RK3288 System on Module.

Signed-off-by: Wadim Egorov w.egorov@phytec.de --- Changes in v3: - Added u-boot,dm-pre-reloc to regulators subnode (PMIC failed to bind because of the missing regulators node) - Removed the hacky PMIC setup from phycore_init - Use CONFIG_TARGET_PHYCORE_RK3288 to cover board-specific stuff

Things get ugly when I use of_machine_is_compatible(). Boards whith CONFIG_SPL_OF_PLATDATA disabled would compile in of_machine_is_compatible() which checks for my board. phycore_init() calls rk818_spl_configure_*() which depends on CONFIG_SPL_POWER_SUPPORT. So this will cause undefined reference linker warnings for every other rockchip board. That's the reason why I moved back to CONFIG_TARGET_PHYCORE_RK3288.
