ARM: dts: qcom: Fix three issues in WLAN converged node

1. Rename vdd-wlan-aon-supply to vdd-wlan-vl-supply to avoid be deleted
   by other platform. Change rfa1/rfa2/rfa3 to vm/sXX/vh as well for
   sa81x5, sa6155 and lxc-vm platform. This issue was introducted from
   commit e9d3bea3, and the regulator of "vdd-wlan-aon" will be
   revmoved from vreg_list in cnss_disable_redundant_vreg().

2. Set unvote flag to 0 to keep fixed voltage for AUTO platform. This
   issue was introduced from the commit 65413acfe6, and some LDOs
   were unvoted after receiving FW ready. This is unexpected behavior
   for the AUTO platform, so that set the need_unvote to 0.

3. Add "address-cells" and "size-cells" property in pcie_rc0 for sa81x5
   and sa6155 platform.
