audioreach-driver: Guard MODULE_IMPORT_NS(DMA_BUF) for kernel < 6.13#64

Conversation
The MODULE_IMPORT_NS macro changed its argument syntax in kernel 6.13.
Before 6.13 it takes an unquoted token (MODULE_IMPORT_NS(DMA_BUF));
from 6.13 onwards it requires a quoted string
(MODULE_IMPORT_NS("DMA_BUF")). Building audioreach_driver against a
pre-6.13 kernel with the quoted form causes a modpost failure because
the namespace import is not recognised, and the build rejects the
module.
Add AR_MODULE_IMPORT_NS to ar_kcompat.h, selecting the correct form
at compile time via LINUX_VERSION_CODE. Replace the bare
MODULE_IMPORT_NS("DMA_BUF") in q6apm_audio_mem.c, with
AR_MODULE_IMPORT_NS(DMA_BUF).
