ACPICA commit 1a3a549286ea9db07d7ec700e7a70dd8bcc4354e

The macros to classify different AML exception codes are broken. For
instance,

  ACPI_ENV_EXCEPTION(Status)

will always evaluate to zero due to

  #define AE_CODE_ENVIRONMENTAL      0x0000
  #define ACPI_ENV_EXCEPTION(Status) (Status & AE_CODE_ENVIRONMENTAL)

Similarly, ACPI_AML_EXCEPTION(Status) will evaluate to a non-zero value
for error codes of type AE_CODE_PROGRAMMER, AE_CODE_ACPI_TABLES, as well
as AE_CODE_AML, and not just AE_CODE_AML as the name suggests.

This commit fixes those checks.

Fixes: d46b6537f0ce ("ACPICA: AML Parser: ignore all exceptions resulting from incorrect AML during table load")
