Add an spl_init() function that does basic init such that board_init_f() can
use simple malloc(), device tree and driver model. Each one is set up only
if enabled for SPL.

Note: We really should refactor SPL such that there is a single
board_init_f() and rename the existing weak board_init_f() functions
provided by boards, calling them from the single board_init_f().

This function can be used for testing to manually request a GPIO for use,
without resorting to the legacy GPIO API.

Provide a driver-model function to look up a GPIO name. Make the standard
function use it.

Commit afbbd413a fixed this for non-driver-model. Make sure that the driver
model code handles this also.

This should say 'in', not 'out'.

gpio_get_values_as_int() should return an error if something goes wrong.
Also provide gpio_claim_vector(), a function to request the GPIOs and set
them to input mode. Otherwise callers have to do this themselves.
