Subject: [PATCH] ARM: dts: qcom: Remove unused mem reservation for wlan

It is confirmed that the following items from device tree will
not be required on auto platforms given these items are only used
by iHelium while auto platforms do not use the same chipset:

  'pil_wlan_fw_mem'
  'wlan_msa_mem'

Those memory blocks reserved by the above dtsi nodes will be
re-allocated to other components.
