[PATCH 1/7] ACPICA: Only include ACPI asm files if ACPI is enabled

[Lee Jones]

Any drivers which support ACPI and Device Tree probing need to include
both respective header files.  Without this patch, if a driver is being
used on a platform which does not support ACPI and subsequently does not
have the config option enabled, but includes linux/acpi.h the build
breaks with:

  In file included from ../include/acpi/platform/acenv.h:150:0,
                   from ../include/acpi/acpi.h:56,
                   from ../include/linux/match.h:2,
                   from ../drivers/i2c/i2c-core.c:43:
  ../include/acpi/platform/aclinux.h:73:23:
   fatal error: asm/acenv.h: No such file or directory
