Input: i8042 - add LoongArch support in i8042-acpipnpio.h 



LoongArch uses ACPI and nearly the same as X86/IA64 for 8042. So modify
i8042-acpipnpio.h slightly and enable it for LoongArch in i8042.h. Then
i8042 driver can work well under the ACPI firmware with PNP typed key-
board and mouse configured in DSDT.
