Subject: [PATCH v2 6/6] ACPI: NFIT: Remove redundant call to to_acpi_dev()

In acpi_nfit_ctl() ACPI handle is extracted using to_acpi_dev()
function and accessing handle field in ACPI device. After transformation
from ACPI driver to platform driver this is not optimal anymore. To get
a handle it's enough to just use ACPI_HANDLE() macro to extract the
handle.
