[RFC PATCH 03/19] global: k3: use gd to store the resume state

[Prasanth Babu Mantena]

From: Richard Genoud <richard.genoud at bootlin.com>

As stated by the README, in board_init_f(), the BSS is not available, so
we cannot use global/static variables, only stack variables and
global_data.

Thus, we use gd to store the resume state of the board.
