Subject: [PATCH] arm64: Explicitly mark 64-bit constant as unsigned long

Makes sparse happy. Before:

arch/arm64/include/asm/sysreg.h:471:42: warning: constant 0xffffffffffffffff is so big it is unsigned long
arch/arm64/include/asm/sysreg.h:512:42: warning: constant 0xffffffffffffffff is so big it is unsigned long
