[PATCH v3 2/2] rockchip: rk3399: fix incorrect ifdef check on SPL_GPIO

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at theobroma-systems.com>

The check to perform is on CONFIG_SPL_GPIO and not SPL_GPIO.
Because this was never compiled in, it missed an include of cru.h that
was not detected before. Let's include it too.

Also switch to IS_ENABLED in-code check as it is the preferred
inclusion/exclusion mechanism.

Fixes: 07586ee4322a ("rockchip: rk3399: Support common spl_board_init")

v3:
 - always include header to fix compilation for boards with
 CONFIG_SPL_GPIO disabled,
 - always define rk3399_force_power_on_reset function by using an
 in-code IS_ENABLED check instead of an ifdef to fix compilation for
 boards with CONFIG_SPL_GPIO disabled,

v2:
 - use IS_ENABLED checks,
