ACPI_HANDLE macro to do the job.

During skl_nhlt_init(), acpi obj pointer is allocated and never
freed and remap address is not unmapped.

To fix this we should release the ACPI obj and also unmap the
nhlt address during cleanup of driver.

The Non-HD Audio Endpoint Description table contains the link
configuration information for the DSP. This is specific to Non HDA
links only, like I2s and PDM

Skylake driver will use NHLT table to retrieve the configuration based
on the link type, format, channel and rate. This configuration is
passed to DSP FW
