qcacld-3.0: add build flag DYNAMIC_SINGLE_CHIP
Introduces a new build flag 'DYNAMIC_SINGLE_CHIP':
If DYNAMIC_SINGLE_CHIP is defined, which means there
are multiple possible drivers, but only requires one
instance of driver at a time. In such case, leave
MULTI_IF_NAME undefined, no matter what the module
name is, only prepend DYNAMIC_SINGLE_CHIP to names
of firmware/mac/ini files.
Take path of driverdump and ini file for example:
If both MULTI_IF_NAME and DYNAMIC_SINGLE_CHIP are not
defined, the paths are:
driverdump: '/proc/debugdriver/driverdump'
ini: '/<fw_root>/wlan/qca_cld/WCNSS_qcom_cfg.ini'
If DYNAMIC_SINGLE_CHIP is defined as 'qca6174':
driverdump: '/proc/debugdriver/driverdump'
ini: '/<fw_root>/wlan/qca_cld/qca6174/WCNSS_qcom_cfg.ini'
If MULTI_IF_NAME is defined as 'qca6174' and
DYNAMIC_SINGLE_CHIP is not defined:
driverdump: '/proc/debugdriverqca6174/driverdump'
ini: '/<fw_root>/wlan/qca_cld/qca6174/WCNSS_qcom_cfg.ini'
On LA platform, DYNAMIC_SINGLE_CHIP is controlled by
TARGET_WLAN_CHIP and TARGET_MULTI_WLAN:
If more than one WLAN devices are enabled in TARGET_WLAN_CHIP,
and TARGET_MULTI_WLAN is not set to 'true',
DYNAMIC_SINGLE_CHIP will be set to the device name, to
avoid name conflicts of firmware/mac/ini files;
meanwhile, MODNAME is set to 'wlan', then paths for
debugging are not changed.
Otherwise, MULTI_IF_NAME will be defined if requires
multiple instances of driver.
