irqchip/tegra: Fix overflow implicit truncation warnings

[ Upstream commit 443685992bda9bb4f8b17fc02c9f6c60e62b1461 ]

Fix -Woverflow warnings for tegra irqchip driver which is a result
of moving arm64 custom MMIO accessor macros to asm-generic function
implementations giving a bonus type-checking now and uncovering these
overflow warnings.

drivers/irqchip/irq-tegra.c: In function ‘tegra_ictlr_suspend’:
drivers/irqchip/irq-tegra.c:151:18: warning: large integer implicitly truncated to unsigned type [-Woverflow]
   writel_relaxed(~0ul, ictlr + ICTLR_COP_IER_CLR);
