brcmfmac: fix invalid access to struct acpi_device fields
The fields of struct acpi_device are only known when CONFIG_ACPI is defined. Fix this by using a helper function. This will resolve the issue found in linux-next: ../brcmfmac/bcmsdh.c: In function 'brcmf_ops_sdio_probe': ../brcmfmac/bcmsdh.c:1139:7: error: dereferencing pointer to incomplete type adev->flags.power_manageable = 0; ^ Fixes: f0992ace680c ("brcmfmac: prohibit ACPI power management ...")
