Use readl/writel for ARM64 instead of __raw versions.
This patch also remove compilation warnings:
drivers/gpio/gpio-xilinx.c: In function ‘xgpio_irq_mask’:
drivers/gpio/gpio-xilinx.c:300:12: warning: large integer implicitly
truncated to unsigned type [-Woverflow]
            ~XGPIO_GIER_IE);
            ^
drivers/gpio/gpio-xilinx.c:48:51: note: in definition of macro
‘xgpio_writereg’
 # define xgpio_writereg(offset, val) __raw_writel(val, offset)
