qcacld-3.0: Add support for sae roaming with single PMK

Requirement is to allow station to just keeps only one
PMK1 and PMKID1 which gets derived while first connection
and re-use it for roaming to other AP which has some
specific VSIE.

To support this feature, STA should:
1. Set new flag in 11i params during RSO start/update when
initial connection is completed based on the VSIE in AP
beacon/probe response frame. This flag will allow fw to roam
to AP(s) which has VSIE with single PMK.
2. STA should dynamically enable this feature if below
vendor specific IE on AP’s Beacon or Probe Response at
the first connection:
Category 	Data
Type 		0xDD
Length 		0x05
OUI 		0x00 40 96
Type 		0x03
Data 		Don’t care
		(EX, 0x05)

Maintain a separate pmk information structure to support sae
roaming using single pmk.
