[qca-nss-drv]: Add support for retrieving NSS FW logs from HLOS
This commit adds support in qca-nss-drv to retrieve NSS FW logs
from HLOS by running cat/tail command on file
/sys/kernel/debug/qca-nss-drv/logs/core0 (core-id 0) or file
/sys/kernel/debug/qca-nss-drv/logs/core1 (core-id 1). We can
also run 'tail -f <file>'
