[U-Boot] [PATCH v2 05/21] pmic: Introduce power_board_init() method at ./lib/board.c file

[Lukasz Majewski]

It is necessary to introduce a new system wide function- power_board_init()

It turns out, that power initialization must be done as early as possible.
In the case of PMIC framework redesign, which aims to support multiple
instances of PMIC devices the initialization shall be performed just
after malloc configuration.

The arch_early_init_r() could be used instead, but it doesn't reflect
that the "power" subsystem is going to be initialized.
