ath11k: Add debugfs interface to configure firmware debug log level

Add debugfs interface "fw_dbglog_config" to configure firmware log level.
Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID.

Command to configure,
echo "<dbglog_param> <values>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config

where dbglog_param can be,
  1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module
     here, <values> = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel
  2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev
     here, <values> = vdev_id
  3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev
     except ERROR logs
     here, <values> = vdev_id
  4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap
       here, <values> = vdev_enable_bitmap
  5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the
     modules specified in the module bitmap. Command to configure for this log param,

     $ echo "5 <values> <module_id_index> <is_end>" >
         /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
     here,
                <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
                          'bb' - loglevel
                <module_id_index> = index of module bitmap. Max module id is 512.
                                    So, module_id_index is 0-15.
                <is_end> = to indicate if more configuration to follow.

  6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable.
     Command to configure for this log param,

      $ echo "6 <values> <module_id_index> <is_end>" >
          /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
      here,
                 <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
                              'bb' - loglevel
                 <module_id_index> = index of module bitmap. Max module id is 512.
                                     So, module_id_index is 0-15.
                 <is_end> = to indicate if more configuration to follow.

Sample command usage,

To enable module WLAN_MODULE_WMI and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "1 0x10001" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config

To enable module bit map from 32 to 63 and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "5 0xffffffff00000001 1 1" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
