icnss2: Vote for chain1 regulators if RD card is 2x2

Browse source 
Wlan fw will provide RD card chain mask capability
for as part of cap qmi message exchange between host
platform and fw platform. Using this info host platform
will determine whether RD card chain is 1x1 or 2x2. It
will enabled chain1 regulator if RD card is 2x2 and also
if wlan fw doesn't provide any details about RD card
chain mask capability chain1 regulator will enabled
by default.
