kernel: Adding FLAGS required by the wifi.

BZ: 15061

Actually, the wifi driver is based on compat wireless modules that
requires WL12XX_PLATFORM_DATA to be enabled within the kernel. So
it shall be enabled by default with WL12XX.

The wifi uses two AON gpios and thus the wifi interrupt handler is
forwarded by the GPIO driver. So to prevent losing wifi interrupts,
HARDIRQS_SW_RESEND shall be used.
