Wlan: Disable compiling Wlan Driver Module for 8x16 target

With enabling of  WLAN driver on 8x16 target, errors observed while
compiling in 64-bit mode due to the target name being common for
32-bit  and 64-bit. So disabling WLAN driver compilation until
the 64-bit compilation issues are resolved.

wlan: SAP is able to select channels marked as unsafe.

If channel no. 14 is present in the 20Mhz scan list
the algo  is not able to populate channels higher than 14.
If SAP  scan results are NULL, SAP is able to select unsafe
channel( 1st channel from the sapContext->channelList ).

Adds the logic to process channel higher than 14.
Populate the SAP scan list(sapContext->channelList) only
with safe channels, so if scan result are NULL,
it will only select safe channel.
