Subject: [PATCH] spi: tegra20: fix build with CONFIG_PM_SLEEP=n

From: Arnd Bergmann <arnd@...db.de>

There is another one of these warnings:

drivers/spi/spi-tegra20-slink.c:1197:12: error: 'tegra_slink_runtime_resume' defined but not used [-Werror=unused-function]
 1197 | static int tegra_slink_runtime_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~

Give it the same treatment as the other functions in this file.

Fixes: efafec27c565 ("spi: Fix tegra20 build with CONFIG_PM=n")
Fixes: 2bab94090b01 ("spi: tegra20-slink: Declare runtime suspend and resume functions conditionally")
