gpio: zevio: allow COMPILE_TEST builds

Browse Source 
The ZEVIO GPIO driver uses generic platform, MMIO, and gpiolib interfaces.
Allow it to build with COMPILE_TEST so it gets coverage on non-ARM
platforms.

Drop the ARM-specific IOMEM() casts around the register pointer.  The
pointer is already __iomem, so readl() and writel() can use it directly.

Tested with:
make LLVM=1 ARCH=loongarch drivers/gpio/gpio-zevio.o
