[PATCH v2 05/11] gpio: vf610: drop unnecessary wrappers

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Remove trivial wrapper functions vf610_gpio_writel() and
vf610_gpio_readl() that just called the relaxed versions directly.
Replace their usage with direct calls to writel_relaxed() and
readl_relaxed().
