[PATCH 1/2] mtd: rawnand: lpc32xx_mlc: Switch to using pm_ptr()

[Geert Uytterhoeven]

The switch to using the gpiod API removed the last user of
lpc32xx_wp_disable() outside #ifdef CONFIG_PM, causing build failures if
CONFIG_PM=n:

    drivers/mtd/nand/raw/lpc32xx_mlc.c:380:13: error: ‘lpc32xx_wp_disable’ defined but not used [-Werror=unused-function]
      380 | static void lpc32xx_wp_disable(struct lpc32xx_nand_host *host)
          |             ^~~~~~~~~~~~~~~~~~

Fix this by switching from #ifdef CONFIG_PM to pm_ptr(), increasing
compile-coverage as a side-effect.
