Subject: [PATCH] pinctrl: at91-pio4: Make PINCTRL_AT91PIO4 depend on HAS_IOMEM to fix build error

If CONFIG_HAS_IOMEM is not set, devm_platform_ioremap_resource() will
be not built in drivers/base/platform.c and then there exists a build
error about undefined reference to "devm_platform_ioremap_resource"
in pinctrl-at91-pio4.c under COMPILE_TEST and CONFIG_PINCTRL_AT91PIO4,
make PINCTRL_AT91PIO4 depend on HAS_IOMEM to fix it.
